oa Bacterial Kinetics for Control Shape and Biogenic Synthesis of Nanoparticles: Review

Nanoparticles have many applications, such in health, agriculture, etc. One of these essential nanoparticles is silver (Ag), which can be applied for drug delivery like encapsulation cause silver (Ag) nanoparticles have excellent antibacterial activity towards both human strains. In addition, silver synthesis can be explored by electrochemical approaches on bacterium after exposure to silver (Ag). The synthesis of nanoparticles can be achieved by biogenic synthesis, for instance, Morganella psychro-tolerant, silver-resistant psychrophilic bacteria. Morganella psychro-tolerans is a good bacterium with the same character as the Morganella morganii synthesizing silver nanoparticles. The ability of Morganella morganii was expressed due to its specificity to maintain high deliberation of silver (Ag) through the cell synthesis of rounded silver (Ag) nanoparticles and its ability to grow at a lower temperature range (psychros: cold) in the temperature range of 0-30 ^oC. Anisotropy form of silver nanoparticles can be attained by controlling this bacteria growth kinetics. This synthesis system can be employed by a green biosynthetic approach to achieve shape control of nanoparticles, which is an environmentally friendly, large-scale, and economical process. This review discusses Morganella psychro-tolerant for controlling shape and biogenic synthesis from related aspects such as the synthesis mechanism, the influencing factors like shape and size, the application method, and its development.
