  • Quantam-dot based drug delivery for antimicrobial resistance

Broad research Area My research area involves drug delivery against neglected tropical diseases like leishmaniasis using nanoparticles. Further, drug delivery against fungal and bacterial infections using quantam dot are also explored. Delivery of drugs followed by identification of mechanism of action using biochemical, molecular biology and proteomics approach is the area of our expertise. Generation of recombinant proteins, enzyme assay and drug binding interactions with ITC and CD are done to quantify the drug-target binding interactions. In our recent work, we have identified natural compounds like medium chain fatty acids (caprylic acid), flavonoids (7, 8-dihydroxyflavone) etc. as key antiparasitic agents. The ergosterol biosynthesis and polyamine biosynthesis pathway of parasite was found to be the key target for these antileishmanial agents. We have developed an AmB-based silver NP (AmB-AgNP) which is highly selective in biding with ergosterol but not with cholesterol. The AmB-AgNP has good antileishmanial and anti fungal efficacy. In another work, we are exploring antibiotic synthesized quantam dots as antimicrobials for multi-drug resistant bacteria with possible mechanism of action. We have recently checked the specific nanozyme activity of a QD synthesized from coal waste. The kinetics, ITC and biological studies have proven that the QD is highly specific for superoxide dismutase activity. We are trying to develop a polypeptide vaccine composed of fused peptides of Leishmania origin. The high immunogenicity and TLR binding of the vaccine construct was confirmed by immunoinformatics studies.
