A cross-linking process was used to prepare hydrogel foams by just adding 3 components: an NCO-terminated three-arm prepolymer, SAP particles, and water. Variations in the chemical compositions allow creation of hydrogel foams with different material properties that can be applied to wounds with different characteristics. Hydrogel foams that are stable to electron beam sterilization are mechanically stable and have adjustable as well as very high absorption capacities. SAP-loaded foams have open pore structures and can be used to remove excess exudate from highly exudating wounds. Additionally, the SAP-loaded hydrogels have tunable high moisture donation properties and, hence, the potential to help keep contaminated wounds clean or to moisten a dry wound to enhance wound healing. Therefore, hydrogel foams with SAP particles have the potential to be used in advanced wound dressings for application on both dry and highly exudating, acute, and chronic wounds.","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polymeric particles provide remarkable versatility due to their adaptable physiochemical properties, facilitating new designs that address complex delivery issues. This review focuses on recent advancements in the morphology of polymeric particles that emulate biological barriers to improve drug efficacy. It includes how structural engineering─such as designing rod-shaped particles for improved cellular uptake, red-blood-cell-shaped particles for prolonged circulation, worm-shaped carriers for improved tissue penetration, and multicompartmental systems for providing combination therapies─profoundly alters drug delivery capabilities. These designer particles exhibit enhanced target specificity, controlled release kinetics, and improved therapeutic outcomes relative to traditional spherical carriers. This particular review also emphasizes how a combination of polymer chemistry and fabrication methods facilitates achieving these advanced structures, while highlighting ongoing challenges in scale-up, reproducibility, and clinical translations. Through the analysis of structure-functional property correlations in various biomimetic designs, we have also attempted to provide insight into future advancements in polymeric delivery systems that have the potential to transform treatment strategies for complicated diseases via shape-directed biological interactions for better therapeutic outcomes.","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple causes, such as mechanical failure, inadequate osteointegration, and corrosion, lead to implant failure over time. This study seeks to resolve these challenges by surface-modifying biodegradable materials such as poly(lactic acid) (PLA) and AZ31 Mg alloy (Mg), integrating novel Biocomposites of titanium-hydroxyapatite (Ti-HA) to improve their efficacy. The altered materials aim to enhance mechanical strength, osteointegration, and regulated deterioration, thus minimizing the likelihood of implant failure. The characterization techniques validated the Biocomposites' adhesion on the implant's surface, mechanical analysis and corrosion resistance were also validated with the help of UTS and electrochemical studies, and in vitro analyses exhibited substantial improvements in material durability and biological compatibility. The result shows that the Biocomposite assistance improved the overall performance of the implant material. This work presents a pioneering strategy to mitigate implant failure by emphasizing these enhancements, facilitating more dependable and efficient solutions in orthopedic implantation, ultimately enhancing patient outcomes and decreasing the necessity for revision procedures. The earlier segment of the research study was confirmed with another Biocomposites (Ti-Zr), representing a continuation of that research work.","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144118328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lack of systematic data on the correlation between environmental parameters and microbial growth has hampered the development of targeted solutions to date. To address this challenge, this study reports a targeted strategy to inactivate and control the proliferation of commonly identified fuel-contaminating microbial clusters through the development of synthetic peptides that can be delivered directly to fuel samples. From a library of short peptides which was designed based on the indolicidin template peptides, three unique sequences were found to have good broad-spectrum activity toward a range of microbes such as Bacillus, Sphingomonas, and Hormoconis, with P17, showing the highest killing potential. The structural analyses of the peptides based on circular dichroism spectroscopy revealed the helical propensity of the peptides in SDS micelles and a random flexible structure in solution. The peptides showed stability under biological conditions and minimal cytotoxicity against mammalian cells. This study presents an innovative method to effectively address fuel biocontamination using short peptides coupled with a potentially scalable protocol to administer the peptides to fuel samples.","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144118330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prior to in vivo imaging, the administration of a bolus injection of paramagnetic species, coined as contrast agents (CAs), has become almost routine to facilitate conspicuous imaging in a relatively short measurement period. The contrast agents are mainly small Gd(III)-complexes of macrocyclic and acyclic organic ligands with polar pendant arms. Nonetheless, reports on some adverse effects due to the accumulation of bare Gd(III) ions in the human body from the used gadolinium-based contrast agents necessitate extensive investigations on Mn(II)-complexes to engender potential alternatives. While thermodynamically stable and kinetically inert Mn-complexes with inner-sphere water molecule(s) have been developed and tested as CAs, the enhancement in the relaxivity value beyond 3.5 mM-1 s-1 has been intriguing. This review discloses the recent strategies for incorporating paramagnetic small Gd(III) and Mn(II) complexes within the porous nanosystems, the physicochemical properties, and stability and contrast efficiency improvement after confinement. The generation of \"smart\" and environmentally responsive contrasting probes by incorporating appropriate functional groups onto the surface of the robust nanosystems is also presented herein.","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144118338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is crucial to effectively eliminate melanoma and promote rapid and healthy regeneration of postoperative tissue defects. Herein, hesperidin derivatives (HD) have been developed as the bioactive components of hydrogels that are capable of ablating melanoma via photothermal therapy (PTT) and promoting tissue regeneration. HD have been prepared by heating hesperidin alkaline solution followed by dialysis and lyophilization, and GelMA hydrogels encapsulating HD kill cancer cells and bacteria under near-infrared (NIR) irradiation. The in vitro test and in vivo transcriptomic analysis confirmed that the HD containing GelMA hydrogels induce the immunogenic cell death (ICD) effect of tumor cells by significantly upregulating chemokine-related, cytokine-related, and apoptosis-related genes, thereby enhancing therapeutic efficacy. In a mouse model of infected skin wounds, the HD containing hydrogels under 808 nm light irradiation effectively promoted wound repair. This was achieved through accelerated wound closure and enhanced skin regeneration, mediated by increased angiogenesis and collagen deposition. In conclusion, the HD containing hydrogels provide a new strategy for the clinical treatment of melanoma and postoperative tissue defect repair following operative resection of cancer.","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144109018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the clinical translation of nanoparticle-based therapeutics remains challenging, primarily due to an incomplete understanding of how nanoparticle properties influence interactions at the nano-bio interface, as well as the role of surface-adsorbed proteins (i.e., protein corona) in modulating nanoparticle-cell interactions. This study demonstrates that the surface charge has a greater influence than protein corona formation in determining the cytotoxicity, cellular uptake, and biodistribution of AgNPs. Using negatively and positively charged AgNPs, we show that while protein corona formation is essential for ensuring nanoparticle availability for cellular interactions, the adsorption of biomolecules is nonspecific and independent of surface charge. Conversely, the surface charge significantly influences the interactions of AgNPs with cells. Positively charged nanoparticles exhibit enhanced cellular uptake, preferential accumulation in lysosomes, and pronounced mitochondrial damage compared to their negatively charged counterparts, resulting in greater cytotoxic effects. This effect is particularly evident in human breast cancer cells, where negatively charged nanoparticles show minimal uptake and cytotoxicity. These findings demonstrate that surface charge is the primary factor governing nanoparticle-cell interactions rather than protein corona formation. Nonetheless, the protein corona plays a critical role in stabilizing nanoparticles in physiological environments.","PeriodicalId":2,"journal":{"name":"ACS Applied Bio Materials","volume":" ","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144109024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
