Several characterization methods verified the production of PFE-CuFe2O4 NPs. The absorption spectrum exhibited the peak at 420 nm; band gap of 1.85 eV. The studies of SEM and TEM confirmed spherical and homogeneously distributed CuFe2O4 NPs with an average size of 22.4 ± 1.4 nm. The FTIR reported the presence of bio-essential molecules in PFE can act as a stabilizing and capping agent. The NPs were found to be fairly stable with zeta potential found at 28.9 ± 0.2 mV. Numerous in vitro biological investigations exemplified the applicability and practicality of CuFe2O4 NPs and compare them with the standard. The biofunctionalized CuFe2O4 NPs demonstrated a potent antibacterial activity against E. coli and S. aureus. Additionally, it was discovered that CuFe2O4 NPs have superior antioxidant activity (77-83%) and their scavenging ability is more comparable to ascorbic acid (control). Furthermore, a degradation efficiency of 91-92% was observed in 10-15 min for CuFe2O4 NPs in rhodamine B (RhB) and methylene blue (MB) dyes, indicating their remarkable effectiveness in this regard. Future research may focus on applying CuFe2O4 NPs to comprehensive wastewater treatment and determining the degradation products and ecological consequences.","PeriodicalId":72828,"journal":{"name":"Discover nano","volume":"20 1","pages":"99"},"PeriodicalIF":0.0,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12209143/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144531389","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}

Nanomaterials exhibit very peculiar thermal, mechanical, electrical, optical, and chemical properties compared to their bulk counterparts. When a bulk material is chopped to a nano-dimension, electrons are subjected to peculiar boundary conditions, eventually leading to the nanomaterials' special properties. Due to their exceptional properties, nanomaterials have unique applications in all branches of science. Consequently, the researchers explored many methods of synthesis of the nanomaterials. However, each method has its advantages and disadvantages, some methods are flexible in synthesizing nanoparticles with uniform size distribution and some are feasible to produce nanomaterials at higher yields. Different methods follow their own synthesis protocols, time durations, economical feasibility, and reproducibility. Most methods complement one another by producing nanomaterials of evenly distributed sizes, shapes, properties, etc. Amongst, the, laser ablation of metals/semiconductors/insulators immersed in a liquid medium is a well-known method of green synthesis of nanomaterials that utilizes no hazardous chemical precursors. Laser ablation in liquids (LAL) combines top-down and bottom-up approaches that do not require lengthy sample preparations, chemical surfactants, and sophisticated experimental methodologies.

The developed technique is based on the Localize Surface Plasmon Resonance (LSPR) band intensity quenching, accompanied by a red shift in the wavelength range 523-545 nm at higher concentrations, due to interaction between U(VI) ion and phosphate group bearing PB2MEP-Au. The response was linear in the 5-80 ppb U(VI) concentration range, with LOD of 8.6 ppb. Samples were characterized by transmission electron microscopy, Particle Size Analysis and Zeta Potential measurements to determine morphological transitions upon analyte interaction. Density Functional Theory (DFT) calculations were invoked to study the Au nanoparticle stabilization mechanism, and revealed the interaction of U(VI) with PB2MEP-Au to be thermodynamically spontaneous for the formation of [UO2(B2MEP)2(H2O)]2+ complex, the stability primarily driven by entropy. Interference by other coexisting metal ions was negligible up to interferent:target ratios of 10:1. The method was validated through quantification of U(VI) in water samples spiked with known U(VI) concentrations, the results being in corroboration with those reported using laser fluorimetric method. A T-test confirmed the results derived from the proposed method were not significantly different from those obtained using the standard estimation protocol at a 95% confidence level.","PeriodicalId":72828,"journal":{"name":"Discover nano","volume":"20 1","pages":"95"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12170492/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144303782","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, the use of platinum which is a rare and expensive counter electrode (CE) hinders the widespread application of DSSCs, necessitating the use of cheap, abundant, and efficient materials. The review therefore focuses on carbon-based nanomaterials specifically carbon nanotubes (CNTs) and graphene as CEs in DSSCs. The CE plays a vital role in regenerating the redox couple, and its charge transfer resistance (Rct) should ideally be 1 Ω cm² for optimal performance. Carbon nanotubes comprising single-walled carbon nanotubes (SWCNTs), double-walled carbon nanotubes (DWCNTs), and multiwalled carbon nanotubes (MWCNTs) are mainly prepared by chemical vapor deposition (CVD). The SWCNTs have achieved an efficiency of 7.79%, comparable to platinum electrodes, and this was due to the morphology, which influenced the redox mediator regeneration but also reduced the Rct. In addition, graphene with high transparency (97.7%), large specific surface area (2630 m2 g- 1), excellent thermal conductivity (3000 W m- 1 K- 1), and good carrier mobility properties (10,000 cm2 V- 1 S- 1) have also been applied. In this, the Graphene nanosheets demonstrated a 6.81% efficiency, comparable to platinum (7.59%) due to a high open circuit voltage (Voc), which accounts for the reduction of iodide/triiodide redox couple. Lastly, the Graphene nanoplatelets demonstrated a 9.3% efficiency comparable to that of Platinum 7.53% due to low charge transfer resistance, high electrocatalytic activity, and good fill factor.","PeriodicalId":72828,"journal":{"name":"Discover nano","volume":"20 1","pages":"94"},"PeriodicalIF":0.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12170987/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144303781","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}

This growing prevalence imposes immense societal and economic burdens on healthcare systems and caregivers. AD is challenging to treat with monotherapy, making combination therapy a more effective approach. This study focuses on delivering Rivastigmine tartrate (RIV), and Nilotinib hydrochloride monohydrate (NIL), to the brain to achieve synergistic effects against AD. The optimal ratio of the drug combination was determined using the combination index that was performed using the Neuro2a cells line. It was found to be 1:1, emphasizing the synergistic effect against the cell lines. So, nanostructured lipid carriers (NLCs) were loaded with RIV and NIL, both individually and in combination, developed and optimized in this study. The developed formulations were thoroughly characterized for globule size, polydispersity index (PDI), and entrapment efficiency (EE) for each drug and the combination. The globule size was > 200 nm, PDI > 0.3; EE < 85% in all the developed formulations. On performing an in vitro cell availability study it was found that developed NLCs showed a 1.3 to 1.4-fold increase in the viability of the cells. On conducting an in vivo study, the concentration in the brain following administration of different formulations was in the order of RIV-NIL-NLC > NIL-NLC > RIV-NLC > RIV-NIL SUS > NIL-SUS > RIV-SUS. There was a 3.5 to 5-fold increase in the concentration of RIV and NIL in the brain when administered as RIV-NIL-NLC.
