    In this talk the current status of an ongoing effort in the Electrical Engineering Department at IIT Bombay on the development of an integrated systems to provide point-of-care diagnostic support for cardiovascular diseases will be presented. The system under development monitors the molecular...

  12. Self-association of peptides and proteins: Retrospect and prospects

    30 Jul 2008 | | Contributor(s):: R. Nagaraj

    The ability of peptides and proteins to form aggregates was known from the dawn of protein and peptide chemistry! It was often considered a nuisance and attention was directed towards disaggregating them to ensure dissolution particularly in aqueous solution. X-ray crystallography has indicated...
