The recent study deals with the synthesis and characterization of silver nanoparticles bounded to Selaginella bryopteris (Sanjeevini) Plant extract (SPE) as reducing and capping agents. Selaginella bryopteris plant extract silver nanoparticles (SPE@Ag-NPs) was characterized by PXRD, UV-Vis., FESEM, TEM and EDX. The highly stable SPE@Ag-NPs was found promising as antibacterial and antifungal agents when tested against human pathogens S. aureus, E. coli, and A. niger respectively. Furthermore, SPE@Ag-NPs found to show anticoagulant property by enhancing the clotting time of citrated human PRP as well as PPP from the control 160 s to 220 s and 160 s to 284 s respectively. However, SPE@Ag-NPs exhibited mild antiplatelet activity by inhibiting specifically agonist ADP induced platelet aggregation of about 23% at the concentration of 30 μg. Fascinating, SPE@Ag-NPs did not alter the agonist epinephrine-induced platelet function even at the increased dose. Interestingly, SPE@Ag-NPs did not induce edema and hemorrhage in the experimental mice and also did not hydrolyze RBC cells suggesting its nontoxic property. In conclusion, SPE@Ag-NPs was non-toxic and found to exhibit antibacterial, antifungal, anticoagulant and antiplatelet properties. Thus, SPE@Ag-NPs would be a better candidate in the biomedical field especially to treat thrombotic disorders.

In the fast-paced quest for early cancer detection, noninvasive screening techniques have emerged as game-changers, offering simple and accessible avenues for precession diagnostics. In line with this, our study highlights the potential of silver nanoparticle-decorated titanium carbide MXene nanosheets (TiC_AgNPs) as an electroactive interface for the noninvasive diagnosis of oral carcinoma based on the prevalence of the salivary biomarker, tumor necrosis factor-α (TNF-α). An in situ reduction was utilized to synthesize the TiC_AgNPs nanohybrid, wherein TiC acts as the reducing agent, and the resulting nanohybrid was subjected to various characterization techniques to examine the optical, structural, and morphological attributes.

Although fluorescence analysis methods are widely used in pesticide residue detection, improving their sensitivity and selectivity remains a challenge. This paper presents a novel ratio fluorescence sensor based on the molecular imprinting polymers (MIPs) and metal-enhanced fluorescence for visual detection of dicamba (DIC). Calcium fluoride (CaF) quantum dots (QDs) were immobilized on the surface of Ag@MIPs, resulting in a blue fluorescence response signal (Ag@MIPs-CaF).

Electron release and transfer are pivotal to the efficiency of multiple biogeochemical and pollutant processes. Despite substantial efforts to develop electron-transfer characterization techniques, visualization of electron transfer remains challenging. This study introduces an innovative strategy for mapping electron-transfer distance using nanoscale zerovalent iron (nZVI) as a case study.

The isolated Aspergillus flavus NSRN22 was used for green synthesis of silver and selenium nanoparticles (AgNPs and SeNPs). New food packaging films produced by combining each type of NPs with chitosan (CS) or sodium alginate (SA) were characterized. Transmission electron microscopy revealed that the average particle size was lower in case of AgNPs (9 to 14.
