Zinc oxide nanoparticles have been biosynthesized with the help of leaf and fruit extracts. ZnO nanoparticles were tested for antibacterial activity before and after calcination against Gram positive () as well as Gram negative micro-organisms () within the concentration range 0.625-10 mg/mL with the help of well diffusion technique.

Non-Antibacterial and Antibacterial ZnO Nanoparticles Composed of Different Surfactants.

Zinc oxide nanoparticles were synthesized using different surfactants such as SDS, CTAB, Triton X-100, PVP K-30 and ethylene glycol. ZnO NPs were tested for antibacterial activity before and after calcination against different micro-organisms like and (Gram negative) as well as and (Gram positive). Antibacterial activity was observed in SDScapped ZnO NPs only against .

Use of nanotechnology in combating coronavirus.

Recent COVID-19 pandemic situation caused due to the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affected global health as well as economics. There is global attention on prevention, diagnosis as well as treatment of COVID-19 infection which would help in easing the current situation. The use of nanotechnology and nanomedicine has been considered to be promising due to its excellent potential in managing various medical issues such as viruses which is a major threat.

Synthesis and Antimicrobial Properties of Zinc Oxide Nanoparticles.

With increase in incidence of multidrug resistant pathogens, there is a demand to adapt newer approaches in order to combat these diseases as traditional therapy is insufficient for their treatment. Use of nanotechnology provides a promising alternative as antimicrobial agents as against traditional antibiotics. Metal oxides have been exploited for a long times for their antimicrobial properties.

A Review on Antimicrobial Properties of Metal Nanoparticles.

The field of nanotechnology elaborates the synthesis, characterization as well as application of nanomaterials. Applications of nanoparticles in various fields have interested scientists since decades due to its unique properties. Combination of pharmacology with nanotechnology has helped in development of newer antimicrobial agents in order to control the ever increasing multidrug resistant micro-organisms.

Non-antibacterial as well as non-anticancer activity of flower extract and its biogenous silver nanoparticles.

Silver nanoparticles were synthesized by using the white flower extract of Albizia lebbeck as a source of reducing and capping agents. A. lebbeck white flower extract and silver nanoparticles were checked for their antibacterial activity against Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa and Ba cillus subtilis by using Mueller Hinton agar, nutrient agar and Luria Bertani agar using the well diffusion method.

Effect of Nutrient Media on Antibacterial Activity of Silver Nanoparticles Synthesized Using .

Silver nanoparticles synthesized using leaf and fruit extracts which were centrifuged at different speeds (rev/min) were screened for anti-bacterial activity by using four human pathogens namely , (Gram negative) and , (Gram positive). The silver nanoparticles showed good anti-bacterial activity against gram-positive as well as gram-negative bacteria. Nonetheless, silver nanoparticles synthesized using leaf extract has shown pre-dominant anti-bacterial activity rather than fruit extract.
