Abstract
The development of eco-friendly synthesis protocol for the synthesis of nanoscale materials of different compositions, shapes and sizes is an important area of research in the field of nanotechnology. In this paper, we report on the use of alga Tetraselmis kochinensis in the intracellular synthesis of gold nanoparticles of dimensions 5–35nm. The particles are more concentrated upon the cell wall than on the cytoplasmic membrane, possibly due to reduction of the metal ions by enzymes present in the cell wall and cytoplasmic membrane. These intracellular nanoparticles may have applications in drug delivery, biomedical applications, catalysis, etc.
► First report on biosynthesis of gold nanoparticles using the alga T. kochinensis. ► Simple, eco friendly and cost-effective fabrication of highly stable nanoparticles. ► High nanoparticle concentration on the cell wall aids in catalysis, coatings, etc.
