Nanotechnology has the potential to impact many aspects food and agricultural systems. Food security disease treatment delivery methods new tools for molecular and cellular biology new material for pathogen detection and protection of the environment are examples of the important links of nano technology to the science and engineering of agriculture’s and food systems. In the present study, the red and white color paper flower ethanolic extracts doped with MgS (Magnesium Sulphate) nanoparticles were used to determine their antibacterial activity. Both paper flower ethanolic extracts doped with MgS nanoparticles are having potential antibacterial activity when compared with standard antibiotic erythromycin. The white colored flower extracts doped MgS nanoparticles are having more antibacterial activity than the red colored flower extracts doped MgS nanoparticles. The white flowers may contain active antibacterial component. The combination of Bougainvillea glabra flower extracts and MgS nanoparticle may be suggested as a antibiotic agent because of their active potential to inhibit the bacterial growth.
