Scientific Committee of Targeting Mitochondria awarded Dr Shanta Dhar for her work

 During Targeting Mitochondria 2012, the Scientific Committee awarded Dr Shanta Dhar for her Scientific Contribution.

Dr Shanta Dhar, from University of Georgia, USA, was awarded for her scientific contribution for her work about Mitochondria Targeted Nanocarriers for Delivery of Contrast Agents and Therapeutics.

More information about this work:

Mitochondrial dysfunctions cause many human disorders. A platform technology for carrying bioactive molecules to the mitochondrial matrix could be of enormous potential benefit in therapeutics. We are developing a rationally designed, programmable nanoparticle (NP) platform for diagnosis and targeted delivery of therapeutics for mitochondrial dysfunction related diseases. An optimized formulation for maximalmitochondrial uptake was identified through in vitro screening of a library of charge and size varied biodegradable NPs and the uptake was studied by qualitative and quantitative investigations of cytosolic and mitochondrial fractions of cells treated with mitochondria-targeted blended NPs. The versatility of this platform was demonstrated by studying a variety of mitochondria-acting therapeutics for different applications. These include mitochondria targeting chemotherapeutics for cancer, mitochondrial antioxidant for Alzheimer’s disease, and mitochondrial uncoupler for obesity. On the cardiovascular front, we are developing a longcirculating hybrid NP platform to selectively target macrophages and sense apoptosis for detection of plaque vulnerable to embolism.
