Characterization Of Polymeric Phthalocyanine Nanoparticles Using Dynamic Light Scattering Laser, Satish Kumar Murarishetty

All Capstone Projects

The objective of this study is to use DLS (Dynamic Light Scattering) to analyze polymeric copper phthalocyanine nanoparticles (CuPcNPs). CuPcNPs are synthesized in order to facilitate drug penetration of bacterial biofilms for the treatment of chronic wounds. Microorganisms that reside inside the biofilms of chronic wounds are very resistant to any kind of treatment, even to the host’s own immune system. Therefore we have proposed an alternative method to destroy the microorganisms existing within the biofilms. Photodynamic anti-bacterial chemotherapy (PACT) has received much attention for the past decade due to the multi-drug resistant strands. PACT uses photons, a photosensitizer, and …

All Capstone Projects

Biofilms are now considered ubiquitous in the natural world. Bacterial biofilms have been observed to be extremely heterogeneous, both structurally and with regard to the physiology of the bacterial cells within them. The prevailing conceptual model depicts bacterial biofilms as being made up of microcolonies, which serve as the basic unit of the greater biofilm structure. A major concern with this approach is the frequently observed development of resistance to antimicrobial compounds. A number of elements in the process of biofilm formation have been studied as targets for novel drug delivery technologies. The present study aimed to penetrate biofilm by …

Wound Healing And The Role Of Biomarkers And Biofilms, Mujtaba Khan

All Capstone Projects

An injury to the skin alters the integrity of underlying tissues and microcirculation and thus certainly culminates in a wound. Wound healing is a highly complex, dynamic, interactive and well regulated physiological process involving blood cells, extracellular matrix, parenchyma cells and soluble mediators. It starts with alteration in integrity of tissues and ends with the formation of scar. The process of wound healing is distinguished into Haemostasis, Inflammation, Proliferation and Remodeling. Various cells like platelets, neutrophils, macrophages, lymphocytes, angiocytes, keratinocytes, fibroblasts and factors like platelet derived growth factor, transforming growth factor, platelet derived epidermal growth factors, fibroblasts growth factor, albumin, …

Detection Of Folate Binding Protein, Anwer Unnisa

All Capstone Projects

Cancer is the second leading cause of death despite the anti cancer developments including hormone therapy, radiotherapy, chemotherapy. Chemotherapy includes use of potent drugs such as camptothecin, paclitaxel and mitomycin. These drugs have an effect which is dose responsive, where the drug exposure and cell kill are proportional. This chemotherapy is high dose and has less selectivity for cancer cells and has more toxic effect to normal cells. Such kind of non specific treatment to tumor is causing hurdles in the treatment of cancer by chemotherapy. To overcome this current limitation to chemotherapy, the anti cancer drug with high specificity …

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 …

Synthesis And Analytical Evaluation Of Folate Conjugates For Use In Cancer Cell Detection, Sneha Reddy Kuthuru

All Capstone Projects

Recent clinical studies have shown the importance of folate receptor in drug delivery system as they increase the potency and reduce toxicity of many cancer therapies. The folate receptor alpha ( FR-a) binds with high affinity for folic acid and serves for receptor mediated transport of folate into cells. Folate is necessary for DNA metabolism and thus it is speculated that rapidly dividing cancer cells have an increased requirement for folic acid. It is known that FR-a levels are elevated in specific malignant diseases (solid tumors, leukemia) and thus the FR receptor serves as useful targeting moiety for the diagnosis …

Allergen detection kits are used to determine if sufficient protein was removed from the equipment surfaces during sanitation. One kit on the market is the 3M™ Clean- Trace™ Surface Protein (Allergen) swab tests. The test qualitatively detects the presence of protein based on the biuret reaction and will yield …

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 …
