Abstract :

The fabrication of nanoporous/nanoparticulate composites and their applications via surface patterning with chemicals and bio-chemicals has a direct impact in bio-sensing and bio-separation. Surface patterning on nanoparticles in suspension can be a complex process due to the aggregation of the particles and their Brownian motion in the suspension. An overview of group?s research on nanomaterials and their applications in the separation of nucleic acids (DNA and RNA) from the biological cells will be presented in connection with an industrial collaboration with Q-Bioanalytic, Germany where we have commercialized our nanoparticles for DNA separation. The possibility of affinity interaction of biomolecules i.e., nucleic acid, protein, antibody, microorganisms, etc., through hybrid capture will also be discussed in the context of food quality and hygiene in bio-sensing which has recently been published in Nature publishing group. Separation of toxic and microbial contaminants from water and soil using nanotechnology tool will be discussed with respect to an on-going multinational project with the top researchers from China and an industry from UK. Recent on sensing antimicrobial nanocomposites will be discussed in connection with water technology.
