title: Biosynthesis and wound healing activity of copper nanoparticles.
abstract: Nanotechnologies reinvented the utilities of various substances in healthcare. Copper in its native form (copper ion) has been well studied for its antimicrobial and anti-inflammatory activities. Copper in its nano form could have better biological profile and finds many applications in healthcare. There were reports on synthesis of copper nanoparticles by physical and chemical methods and their biological activities, although these methods have limitations. Biosynthesis of nanoparticles using microbes is an ecofriendly approach helping in the synthesis of biocompatible and stable nanoparticles. With this background in mind, the present study was designed to synthesise copper nanoparticles by Pseudomonas aeruginosa and testing their efficacy in enhancing the pace of wound healing. Culture supernatant was used to synthesise copper nanoparticles. Optimum conditions were selected to maximise the biosynthesis of nanoparticles. Biosynthesised copper nanoparticles (BNCPs) were characterised by Malvern zeta sizer and scanning electron microscopy. Average particle size, polydispersivity index and zeta potential of BNCPs were found to be 110.9 nm, 0.312 and (-) 18.3 mV, respectively. BNCPs was evaluated for its wound healing activity by excision wound model in rat. The pace of wound healing was enhanced by BNCPs compared with copper in native form.
