PEG-HCCs show promise for treating cancer, rebooting blood flow in the brain after traumatic injury and controlling chronic diseases.

PEG-HCCs could be targeted to cancer cells, utilized as a drug delivery vector, and can even be visual-izedex vivo.

Poly(ethylene glycol) functionalized hydrophilic carbon clusters (PEG-HCCs) as antioxidants

I am particularly interested in this area of research since oxidation has been shown to be present in many disease states and injury pathways. Successful implementation of a clinical solution to provide protection against and healing from injurious oxidation pathways could be the answer to curing or alleviating suffering from diabetes, traumatic brain injury, non-alcoholic fatty liver disease and other illnesses. I first discovered the antioxidant capabilities of PEG-HCCs in 2009 and have been pursuing testing in vitro and in vivo with a number of collaborators in the Texas Medical Center hospitals and research centers such as Prof. Robia Pautler, Prof. Christine Beeton and Prof. Thomas Kent, from Baylor College of Medicine; Prof. Ah-Lim Tsai, from the University of Texas Health Science Center Houston; Prof. David Baskin, from the Methodist Hospital Research Institute; and Prof. Jeff Myers, from MD Anderson Cancer Center Houston. We have used the PEG-HCC nanoparticles alone and have also sequestered or covalently attached functionality to the nanoparticles. This has been a fruitful area of research that I want to continue because of its potential impact on many diseases of interest.
