Microbial nanotechnologists

Abstract:
The bacterium Bacillus licheniformis is an expert nanotechnologist, according to scientists in India. They have used the microbe to help them synthesise gold nanocubes, as verified by UV spectroscopy and other techniques. The approach offers an alternative approach to making these important nanoparticles without using high temperatures or toxic solvents.

Kalimuthu Kalishwaralal, Venkataraman Deepak, Sureshbabu Ram Kumar Pandian, and Sangiliyandi Gurunathan of the Department of Biotechnology, at Kalasalingam University, in Anand Nagar, Tamil Nadu, India, have used the bacterial skills of B. licheniformis to make gold nanoparticles just 10 to 100 nanometres across. UV spectroscopy, scanning electron microscopy (SEM), and X-ray diffraction reveal details of the products. B. licheniformis is well known as a microbe cultured for its protease, which is used in biological washing powder.

"Gold nanocubes syntheses have recently emerged in the field of nanotechnology and scientists are exploring various applications of them," Sangiliyandi told SpectroscopyNOW, "recent major applications of nanocubes are tumour cell detection and targeting cancer cells for various kinds of treatments."
