Synthesis, Characterization and Applications of a Novel Platinum-Based Nanoparticles: Catalytic, Antibacterial and Cytotoxic Studies

The facile one-pot synthesis method was used to synthesize platinum nanoparticles (Doxy-Pt (0) NPs) by reduction method with doxycycline drug as reducing and capping agent. The combined platinum nanoparticles were carefully chosen for catalytic reduction of paracetamol as well as used against antimicrobial and anticancer actions with the well diffusion process and by measuring the zone of inhibition in mm against Gram-positive (S. aureus and S. pyogenes) and Gram-negative (E. coli and S. typhimurium). The Ultraviolet–Visible-absorption spectroscopy technique was used to endorse accumulation of (Doxy-Pt (0) NPs) using the distinctive Plasmon absorption maxima at 264 nm. Another technique of X-ray powder diffraction (XRD) pattern was used to confirm the crystalline nature of the prepared Pt (0) NPs. Transmission electron microscopy (TEM) was used to study the particle size of the prepared Pt (0) NPs with a size range of 10–20 nm. The catalytic study showed that the reduction is ~ 99.9% of paracetamol that was consummate in a small period of reaction time (60 s) by competent doxycycline based platinum nanoparticles. The value of K is calculated (rate constant) value for paracetamol catalytic reduction was achieved 7 × 10−2 by drawing InC versus time (s) and the results showed that the reaction is of the first command kinetics. Furthermore, the reduction in breast cancer cell viability and proliferation via PtNPs was found higher as compare to the normal breast cells (CRL-4010). Therefore, the newly prepared Doxy-Pt (0) NPs had a marvelous catalytic, antibacterial and anticancerous action as a catalyst and drug material. The recent discoveries are similarly extendable for the preservation of the aquatic situation in contradiction of the pollution produced by paracetamol, microbial and cancerous actions via a superficial, highly inexpensive, quick and effectual technique.
