Palladium nanospheres incorporated polythiophene nanocomposite: Investigation of potency promising antimicrobial efficacy

Abstract

The investigation of synthetically integrated palladium (Pd) nanospheres embedded polythiophene (PT) nanocomposite through electrostatic interaction for the antibacterial activity against microorganisms namely Escherichia Coli, Vibrio parahaemolyticus, Staphylococcus Aureus, Bacillus subtilis and fungal cultures, such as Aspergillus niger, Aspergillus ochraceus and Candida albicans. The purity of synthesized materials was analyzed using various methods including X-ray diffraction, UV–Vis spectroscopy, Raman spectroscopy; Fourier transformed infrared spectroscopy, Field emission scanning electron microscopy and Energy dispersive X-ray spectroscopy. The incorporated PT-Pd nanocomposite's N2 adsorption/desorption isotherm was used in a Brunauer–Emmett–Teller (BET) examination to determine the specific surface area and normal pore size measurements, which were calculated to be 5.870 m2 g−1 and 3.5 nm, respectively. Agar well diffusion technique was used to test the produced compounds' inhibitory effects over the course of 24 hrs. When compared to gram-positive organisms, this study showed the best response against gram-negative organisms, with no effective activity against fungal organisms. On the other hand, cyclic voltammetry and electrochemical impedance spectroscopy were used to investigate the electrochemical properties of the produced materials, such as electroactivity and conductivity, in order to promote the antibacterial activity. Accordingly, the observed outcomes imply that the PT-Pd based nanocomposite produced in our current framework is a good candidate for a variety of biological and environmental applications.
