Abstract
In the current exploration, photochemical stability and chemotherapeutic appraisal of Cinnamomum camphora (C.camphora) mediated bioactivity via Tellurium/Zirconium nanoparticles (TeZr BNPs) were conducted. The bioactive bimetallic nanoparticles (BNPs) exists a characterization by employing various studies such as UV, XRD, SEM-EDX, DLS, FTIR, HR-TEM, AFM, BET, and XPS analysis. Screening analysis of methanol soluble components in C. camphora extract identified the components in the plant product by HPLC mass spectroscopy. Furthermore, inhibition activities of TeZr BNPs against monoderm (+) and diderm (−) pathogens were tested by the agar contact method. The results of these studies showed the maximum hindrance zone with TeZr BNPs against three different microorganisms: Staphylococcus aureus (ATCC 6538), Escherichia coli (ATCC 8739), and Vibrio cholera (ATCC 14033) showing 28 %, 26 %, and 27 % inhibition, respectively, confirming the inhibitory potential of TeZr BNPs. The sequences of the inhibition zones were as follows: Staphylococcus aureus > Escherichia coli > Vibrio cholera. Further, the cytotoxic potential of C. camphora mediated TeZr BNPs was evaluated by anticancer, antioxidant, and anti-inflammatory activities. The photolysis steadiness of bioactive TeZr BNPs towards photodynamic therapy was confirmed by collagen degradation. This is the first description of bimetallic nanoparticles for degrading collagen. Hence, TeZr BNPs can be effectively applied in photodynamic therapy.
期刊介绍:
Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
