In the present investigation, we report simple, robust and eco-friendly synthesis of silver nanoparticles (AgNPs) using leaf extract of Flemingia wightiana. The leaf extract of F. wightiana acts as reducing agent which reduces the silver ions into FW-AgNPs, as well as stabilizing agent by capping around them. Biosynthesized FW-AgNPs were characterized by different spectroscopic techniques. UV-Vis spectrum showed the characteristic SPR peak between 380 and 460 nm. EDX analysis revealed the presence of metallic silver at 3 keV. XRD analysis clearly revealed that FW-AgNPs are crystalline in nature with FCC structure. TEM analysis depicted the spherical morphology with 20-40 nm in size. DLS analysis showed that average hydrodynamic size and PDI value of FW-AgNPs were found to be 47.6 nm and 4.5 respectively. Biosynthesized FW-AgNPs showed high negative zeta potential value of − 25.3 mV. FTIR analysis revealed the participation of polyphenols and proteins in the bioreduction and stabilization of FW-AgNPs. FW-AgNPs showed strong DPPH and H 2 O 2 scavenging activity with IC50 values of 71.96 and 80.59 µg/mL respectively. Further FW-AgNPs also showed effective cytotoxicity against cancer cells including SKOV3 and COLO205 with maximum inhibition of 83.2% and 75.9% respectively.

“…On the other hand, for nitric oxide scavenging activity, AgNPs displayed 64.04% scavenging, as compared to 45.72% and 88.62% in plant extract and gallic acid standard, respectively, at 100 μg/mL. Similarly, AgNPs at 100μg/mL concentration have shown a significant superoxide scavenging activity of 81.92%, as compared to the 85.35% present in the tocopherol standard [ 90 ].…”

Antioxidant Functionalized Nanoparticles: A Combat against Oxidative Stress

Numerous abiotic stresses trigger the overproduction of reactive oxygen species (ROS) that are highly toxic and reactive. These ROS are known to cause damage to carbohydrates, DNA, lipids and proteins, and build the oxidative stress and results in the induction of various diseases. To resolve this issue, antioxidants molecules have gained significant attention to scavenge these free radicals and ROS. However, poor absorption ability, difficulty in crossing the cell membranes and degradation of these antioxidants during delivery are the few challenges associated with both natural and synthetic antioxidants that limit their bioavailability. Moreover, the use of nanoparticles as an antioxidant is overlooked, and is limited to a few nanomaterials. To address these issues, antioxidant functionalized nanoparticles derived from various biological origin have emerged as an important alternative, because of properties like biocompatibility, high stability and targeted delivery. Algae, bacteria, fungi, lichens and plants are known as the producers of diverse secondary metabolites and phenolic compounds with extraordinary antioxidant properties. Hence, these compounds could be used in amalgamation with biogenic derived nanoparticles (NPs) for better antioxidant potential. This review intends to increase our knowledge about the antioxidant functionalized nanoparticles and the mechanism by which antioxidants empower nanoparticles to combat oxidative stress.

Bhasmais Metallo-medicine and made from metals and minerals. Rajatbhasma or Silver Bhasma belongs to a group of nanoparticles that have medicinal values and are used in Ayurveda as Drugs against various ailments. Clerodendrum inermea traditionally well-accepted plant is used extensivelyin ayurvedic therapeutic formulations, but till date no major steps have been carried out to validate the scientific relevance of synthesized nanoparticles from Rajatbhasma using C. inerme. Therefore, in the present study biosynthesized nanoparticles were characterized by UV–Vis spectroscopy, SEM, FESEM and EDX analysis whereas, a comparative study has also been made to check the antioxidant and antimicrobial activity of synthesized silver and rajatbhasma nanoparticle. The SEM and FESEM analysis revealed that the synthesized nanoparticles are well shaped and the average particle size ranges between 30–90 nm and 10-50 nm respectively. In the case of EDX analysis, the highest peak at ~3Kev in the case of synthesized silver and rajatbhasma nanoparticle supports the formation of silver nanoparticles. Subsequently, antioxidant and antimicrobial activities of the synthesized nanoparticles showed excellent results when compared to the standard. The obtained results may provide support in the field of therapeutics and drug delivery and might prove beneficial as a novel drug candidate against bacterial infection in the future.
