“…The antimicrobial activity of copper nanoparticles against a number of microorganisms has been reported previously. [32][33][34][35][36] However, it is interesting to note that our findings in this study indicate activity against all species tested. The ultimate purpose of this study was to analyze the effect of chitosan on the antimicrobial properties of copper nanoparticles synthesized by chemical means.…”

Copper nanoparticle synthesis has been gaining attention due to its availability. However, factors such as agglomeration and rapid oxidation have made it a difficult research area. In the present work, pure copper nanoparticles were prepared in the presence of a chitosan stabilizer through chemical means. The purity of the nanoparticles was authenticated using different characterization techniques, including ultraviolet visible spectroscopy, transmission electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and field emission scanning electron microscopy. The antibacterial as well as antifungal activity of the nanoparticles were investigated using several microorganisms of interest, including methicillin-resistant Staphylococcus aureus , Bacillus subtilis , Pseudomonas aeruginosa , Salmonella choleraesuis , and Candida albicans . The effect of a chitosan medium on growth of the microorganism was studied, and this was found to influence growth rate. The size of the copper nanoparticles obtained was in the range of 2–350 nm, depending on the concentration of the chitosan stabilizer.

“…Yoon et al [19] reported the antibacterial effects of silver and copper nanoparticles using single representative strains of E. coli and Bacillus subtilis, where the copper nanoparticles demonstrated superior antibacterial activity compared to the silver nanoparticles. Silver and copper nanoparticles supported on various suitable materials, such as carbon, polyurethane foam, polymers and sepiolite have also been effectively used for bactericidal applications [13,14,[20][21][22]. While various hypotheses have been proposed to explain the mechanism of antimicrobial activity of silver nanoparticles, it is widely believed that silver nanoparticles are incorporated in the cell membrane, which causes leakage of intracellular substances and eventually causes cell death [12,15].…”

Infection of dengue virus (DENV) was number of globally significant emerging pathogen. Antiviral dengue therapies are importantly needed to control emerging dengue. Dengue virus (DENV) is mosquito-borne arboviruses responsible for causing acute systemic diseases and grievous health conditions in humans. To date, there is no clinically approved dengue vaccine or antiviral for humans, even though there have been great efforts towards this end. Copper and copper compounds have more effective in inactivation viruses, likes an influenza virus and human immunodeficiency virus (HIV). Purpose in this project was investigated of Infeksi virus dengue (DENV) adalah patogen yang muncul secara global. Terapi antivirus dengue penting diperlukan untuk mengontrol muncul dengue. Dengue virus (DENV) disebabkan oleh mosquito-borne arboviruses yang menyebabkan penyakit sistemik akut dan kondisi kesehatan pada manusia. Sampai saat ini, tidak ada vaksin dengue klinis disetujui atau antivirus bagi manusia, meskipun telah ada upaya besar menjelang akhir ini. Tembaga dan senyawa tembaga memiliki efektivitas dalam inaktivasi virus, seperti virus influenza dan human immunodeficiency virus (HIV). Tujuan dalam proyek ini adalah menyelidiki senyawa antiviral
