Lecture on Silicon nanoporous membranes for biomolecular separation

The department of E&C Engineering organized a lecture by Dr. H. V Balachandra Achar on the topic of Silicon nanoporous  membranes for biomolecular separation as the fourth installment in the lecture series “Advances in Electronics”, on 07 October 2020. The faculty members of various departments of the college attended the lecture and enhanced their understanding of the topic.

Separation of biomolecules based on their size and charge is an important procedure employed in biomolecular analysis. Nanosieve comprising of a semi-permeable membrane with nanometer-sized pores is used for this purpose. Dr. Achar described the fabrication of ultra-thin nanoporous silicon membrane, which can be used as nanosieve, making use of standard microelectronics fabrication techniques. He also talked about the formation of the pores by transmission and scanning electron microscope images and controlled nucleation of silicon nanocrystals so as to get pores at desired locations.

Asst. Professor Ms. Laxmi Shetty welcomed the participants to the talk. Principal Dr. Thirumaleshwar Bhat and Vice Principal Dr. Ganesh Aithal thanked Dr. Achar for sharing his knowledge and introducing the research avenues in the field of nanoparticles.
