Here, we prepared poly(lactic acid) (PLA)-based polymeric NPs using a scalable microfluidics-based method and systematically investigated the impact of purification method (centrifugation versus tangential flow filtration (TFF)) to remove poly(vinyl alcohol) (PVA) on macrophage uptake, anti-inflammatory effects, biodistribution, and protein corona formation. TFF purification demonstrated significantly higher recovery of NPs compared to the centrifugation method, with little-to-no aggregation observed. PVA removal efficiency was superior with centrifugation, although TFF was comparable. NP cellular association, in vitro anti-inflammatory activity, and in vivo biodistribution studies suggested purification method-dependent alterations, which were correlated with protein corona profiles. This study underscores the potential of TFF, combined with microfluidics, as an efficient and high-yield purification method for NPs, and reveals the need for extensive confirmation of NP biological activity alongside physicochemical properties when developing NP therapeutics at-scale.","PeriodicalId":101141,"journal":{"name":"RSC Pharmaceutics","volume":" 1","pages":" 135-146"},"PeriodicalIF":0.0,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11615567/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A GL 20% w/v solution showing optimum viscosity and conductivity, and high encapsulation (89.2 ± 2.13%) was selected. Additionally, TPGS-1000 incorporated in GL reduced the surface tension for better electrospinning and additional free-radical scavenging activity (∼6 fold of blank nanofibers). The central layer was surrounded by upper and lower PCL–GL layers to control the release of the hydrophilic drug (HS). The electrospun PCL : GL layer sustained the release for ∼24 hours. The developed multilayered nanofibrous scaffolds showed accelerated wound healing in a diabetic rat model. Histological analysis of the wound confirmed the accelerated re-epithelialization and reduced inflammatory response. Laser Doppler flowmetry further showed a significant improvement in the blood flow at the wound site at day 14 and day 21, revealing neovascularization. Therefore, the developed multilayered nanofibrous scaffolds provided a plausible method for fabricating regenerative scaffolds for drug delivery and diabetic wound healing.","PeriodicalId":101141,"journal":{"name":"RSC Pharmaceutics","volume":" 5","pages":" 1021-1032"},"PeriodicalIF":0.0,"publicationDate":"2024-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2024/pm/d4pm00130c?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is growing interest in developing nanomaterials that are active in the near-infrared II (NIR II) region (λ = 950–1300 nm) due to the better penetrability and higher tolerance limit of NIR II light by human skin. In this study, the potential of gold nanocapsules (Au Ncap) with a rattle-like structure, consisting of a solid gold bead core and a porous, thin, rod-shaped gold shell was investigated for PPTT. Specifically, the targeted in vitro photothermal activity of Herceptin-conjugated gold nanocapsules that are active in both the NIR I and II regions are explored towards the Her2 positive SK-BR-3 breast cancer cell line. The conjugation of SH-PEG and Herceptin molecules on the surface of gold nanocapsules was validated through a detailed X-ray photoemission spectroscopy (XPS) analysis. The Au Ncap exhibited high photothermal conversion efficiency of 38.6% and in vitro PPTT results showed its excellent cytotoxicity against the SK-BR-3 cell line leading to apoptotic cell death. These findings suggest that this nanostructure can serve as an efficient photothermal agent in the NIR II region showing excellent PPTT activity at a low laser power density of 0.5 W cm−2.","PeriodicalId":101141,"journal":{"name":"RSC Pharmaceutics","volume":" 1","pages":" 124-134"},"PeriodicalIF":0.0,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/pm/d4pm00244j?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main route to stabilise co-amorphous systems is to increase excipient load either in the co-amorphous formulation or via an additional excipient, creating a ternary amorphous system. Increasing excipient load in a formulation can have disadvantages such as producing large oral dosage forms. In this work, the impact of spray drying process parameters on the formation and short-term stability of a drug–drug co-amorphous mixture in the absence of any excipients is investigated. A 9-point design of experiments (DoE) was conducted to assess the impact of atomising gas flowrate and feed flowrate on the co-amorphous formation and stability. It was found that when the outlet temperature was fixed at 50 °C, the atomising gas flowrate had a more significant effect on the physical stability of the co-amorphous mixture than the feed flowrate. Monitoring the stability of formulations at accelerated stability conditions (40 °C per 75% relative humidity) showed that the co-amorphous systems produced at higher atomising gas flowrates, with smaller droplet sizes and subsequent particle sizes, exhibited a higher stability than those produced at lower atomising gas flowrates. Co-amorphous systems produced at the higher atomising gas flowrates remained stable for the 3-month stability testing period demonstrating that the co-amorphous physical stability can be controlled by optimising the spray drying process. The results presented in this study have significant implications for producing co-amorphous drug delivery systems with a high physical stability without the addition of excipients by spray drying.","PeriodicalId":101141,"journal":{"name":"RSC Pharmaceutics","volume":" 1","pages":" 102-113"},"PeriodicalIF":0.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/pm/d4pm00257a?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nanomaterials may lose their synthetic identity after encountering biological fluids (e.g., serum or plasma), and it might lead to unintended outcomes in real-time applications. Despite advances in nanomedicine, clinical translation and overall patient survival using nanoformulations have largely remained elusive. The layer of biomolecules formed around nanoparticles (NPs), often referred to as protein-corona (PC), can impact their physicochemical properties, including size, surface charge/chemistry, chemical composition, solubility, etc. Recently, a few mechanistic evaluations have demonstrated that the formation of a corona layer on nanoparticles can also have a consequential effect on the release profiles of polymeric soft NPs. To evaluate their therapeutic efficacy and resolve discrepancies that exist between in vitro and in vivo results, transition of NPs from their native to the corona-coupled state and its impact on unloading of their cargo need to be understood. Here, we highlight (i) how inherent properties of polymer precursors can affect PC build-up on soft NPs and its impact on cargo-release kinetics and (ii) limitations of existing methods in analyzing PC in complex systems, with emphasis on the impact nano–bio interactions have on the soft nanoparticle-based drug delivery domain.","PeriodicalId":101141,"journal":{"name":"RSC Pharmaceutics","volume":" 1","pages":" 44-58"},"PeriodicalIF":0.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/pm/d4pm00170b?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, they can be used to lower the processing temperature of the drug to prevent its thermal degradation under a hot melt extruder (HME). Six eutectics of RXB were prepared with various carboxylic acid coformers. The eutectic of RXB and MA (1 : 4, mol/mol), which had the lowest melting point, was selected for the HME process. A hydrophilic polymeric matrix was used to prepare the ASD of the selected eutectic. The resultant extruded filament was further subjected to solubility and dissolution studies. We could load up to 25% RXB–MA eutectic in the polymer matrix to yield a complete ASD of RXB–MA at a lower processing temperature of 110 °C. The ASD of the RXB–MA eutectic showed three times the drug release compared to pure RXB. The RXB–MA (1 : 4) eutectic lowered the HME process temperature, further enhancing the thermal stability, solubility and dissolution rate of RXB.

Symptoms often appear between the ages of 35 and 60, with varying severity caused by periods of remission and exacerbation. In addition, children under the age of 16 might develop juvenile rheumatoid arthritis (JRA). According to a 2021 CDC poll, the World Health Organization estimates that 14 million people worldwide suffer with RA, with 0.92% of India's adult population afflicted. Non-steroidal anti-inflammatory drugs (NSAIDs), synthetic disease-modifying anti-rheumatic drugs (sDMARDs), and biological DMARDs are among the current therapeutic interventions. However, these therapies frequently exhibit limitations such as systemic side effects, short biological half-lives, erratic absorption, and frequent dosing regimens. Recent advances in ligand-based nanotechnology have introduced ligands such as folic acid and sialic acid that improve the targeted delivery when conjugated with nanoparticles. This approach has demonstrated efficacy in improving therapeutic outcomes while alleviating the side effects associated with conventional drug delivery systems. This review highlights the key molecular targets in RA, including T cells, B cells, and TNF-α, while exploring novel ligand-based active targeting strategies as innovative therapeutic avenues. Furthermore, it gives in-depth insights into critical molecular targets and their corresponding ligands, emphasizing the rising importance of ligand-based nanotechnology in the development of targeted drug therapy for autoimmune illnesses such as RA. The findings show the potential for these technologies to revolutionize RA therapy by improving medication specificity and reducing side effects via precise novel targeting mechanisms.","PeriodicalId":101141,"journal":{"name":"RSC Pharmaceutics","volume":" 1","pages":" 19-43"},"PeriodicalIF":0.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.rsc.org/en/content/articlepdf/2025/pm/d4pm00133h?page=search","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
