Ruthenium Complexes As Dna Photonucleases In Treatment Of Malignant Skin Carcinoma, Devi Kalyan Karumanchi

All Capstone Projects

A variety of Ruthenium complexes possessing terpyridine complexes as ligands in their coordination sphere have been investigated extensively as DNA photo nucleases in vitro. This work has led to the realization that compounds of Ruthenium bind to DNA purines and that the interactions are of an unprecedented bridging variety. Owing to the molar absorptivity of these complexes in the visible region, direct cleavage of duplex DNA by these complexes requires irradiation in the range of 400-500 nm.

Although the observation of DNA photo cleavage in vitro makes these systems good candidates for further investigation, it does not provide any information …

Using Photoactive Vitamin Nanoparticles As Photodynamic Antimicrobial Chemotherapeutic (Pact) Agents To Treat Chronic Wounds, Rahul A. Khanke

All Capstone Projects

The objective of the proposed study is to develop new materials and methods to manage microbial growth in chronic wounds using phototherapy. Chronic wounds are considered as a worldwide health problem. The most common chronic wounds can be classified into three categories: venous ulcers, diabetic ulcers, and pressure ulcers. Venous ulcers, which usually occur in the legs, account for about 70% to 90% of chronic wounds and can become infected easily. Venous ulcers are sores that develop after veins in the legs have been damaged. These ulcers can penetrate deeply into the skin. Occasionally, if a venous ulcer persists for …
