Formulation Of Coffee Extract As Polymeric Nanoparticles And Studying Their Potential Biological Activities, Nouran Sharaf
Theses and Dissertations
Coffee extract was prepared and optimized (by solvent extraction) and subsequently entrapped into PLGA nanoparticles using single emulsion-solvent evaporation method (using Design Expert software). Dynamic Light Scattering, Scanning Electron Microscope, Fourier Transform-Infrared Spectroscopy and Folin Ciocalteau assay were used to characterize the NPs and to aid in selecting the optimum formulation conditions. The optimized NPs were in-vitro evaluated for their antimicrobial (by agar-well diffusion method), antioxidant (by DPPH assay) and anticancer (by MTT assay) activities. Finally, the release rate study was conducted for the NP sample showing the highly promising results.
The succeeded NP sample, in terms of the most …

Development Of C5ar-Targeted Nanoparticles For Delivery Of Vaccines, Shailendra Bharadwaj Tallapaka Venkata Sesha
Theses & Dissertations
Since the early attempts of Benjamin Jesty at inducing immunity against smallpox and the pioneering work of Edward Jenner, vaccination has been, and continues to remain, the principal method of protection from diseases. However, most of the successful vaccines have been against pathogens that do not have major mechanisms to evade the immune system. So far, many life-threatening diseases like hepatitis C, HIV infection, malaria etc., have been resistant to existing vaccination strategies. Thus, there is an urgent need to develop new vaccination strategies that can generate long-lived protective immunity against such pathogens.
The purpose of this thesis is to …
