Synthesis, structural characterization and catalytic application of citrate-stabilized monometallic and bimetallic palladium@copper nanoparticles in microbial anti-activities

Nanotechnology deals with small chemical materials ranging from 1 to 100 nm, having specific physicochemical properties that are totally different from their bulk materials. In the last few decades, nanotechnology has been gaining a tremendous reputation in the field of biotechnology, electronics, drug delivery, catalysis, and so on. Nanomaterials have size- and shape-dependent properties, which make them totally different from their bulk counterparts, while the bulk materials have size- and shape-independent properties. Due to the surface plasmon resonance, metal nanoparticles show different colors by changing shape and particle size. The nanoparticles with smaller size than the wavelength of electromagnetic radiations and having high penetrating power are efficiently used as conducting materials. the melting point of this material is automatically decreased with decrease in particle size, probably up to,10 nm. Metal nanoparticles are very attractive because of its high mechanical strength, thermal conductivity, electrical conductivity, chemical stability and large surface area.

  • The scanning electron micrographs images of Cu and Pd nanoparticles showed monodisparity and spherical shape as shown in Figure 1A and B corresponding to their size distribution plots
  • It was observed that the average size of bimetallic Pd nanoparticles over Cu nanoparticles nanoparticles measured by nanomeasure software was 380 nm
  • The highly catalytic and antibacterial activities were observed with bimetallic Pd@Cu nanoparticles
  • The antibacterial activities of bimetallic Pd@Cu nanoparticles were found at a maximum level than the used standard antibacterial drug ofloxacin
  • It is recommended that the developed findings in terms of catalytic property and antibacterial activities of the proposed compounds will enable the use of bimetallic nanoparticles in the field of catalysis and nanomedicine
