Effects Of Carboxylated Nanodiamonds On Macrophages During And After Differentiation, Maisoun E. Bani Hani
Effects Of Carboxylated Nanodiamonds On Macrophages During And After Differentiation, Maisoun E. Bani Hani
Biological Sciences Theses & Dissertations
Nanodiamonds (ND) are a carbon-based nanomaterial that are increasingly being proposed for developing novel imaging techniques, as carriers of biomolecules and therapeutic drugs, as coatings for implants, and for other biomedical applications. The exceptional chemical, mechanical, and optical properties of ND make this material suitable in a wide range of fields. The application of ND in the biomedical field is attractive but requires more in-depth investigation into the safety of ND and its interactions with different cells and systems. The effects of ND on the immune system are not fully understood or investigated and there are several controverting reports regarding …
Design Of Drug Nano-Carriers For Study Of Multidrug Resistance In Single Live Cells, Pavan Kumar Cherukuri
Design Of Drug Nano-Carriers For Study Of Multidrug Resistance In Single Live Cells, Pavan Kumar Cherukuri
Chemistry & Biochemistry Theses & Dissertations
Multidrug resistance (MDR) exists in both prokaryotic and eukaryotic cells. MDR is responsible for ineffective treatment of a wide range of diseases, such as infections and cancer. The ATP-binding cassette (ABC) membrane transporters (efflux pumps) are one of the largest and most diverse super-families of membrane proteins found in all living organisms, ranging from bacteria to humans. All ABC transporters share a common structure of four core domains; two transmembrane domains (TMD) with variable sequence and topology and two nucleotide-binding domains (NBD) with conserved sequences. Conventional methods for the study of the efflux functions are radioactively labeled substrates and fluorescent …
Dispersion Of Cytotoxic Properties Of Multi-Walled Carbon Nanotubes Suspended In Biological Solutions With Tween 80: Their Role In Enhancing Killing Effects Of Nanosecond Pulse Electric Fields On Tumor Cell Lines, Bhargava S. Kalluri
Biological Sciences Theses & Dissertations
The objective of this study was to determine whether multi-walled carbon nanotubes (MWCNTs) suspended in the surfactant Tween 80 give an additive killing effect on tumor cells when exposed to nsPEFs. In this study, MWCNTs were suspended in DMEM and RPMI with or without T80 (surfactant). The size distribution of MWCNTs suspended in these solutions was evaluated with a Delsa™ Nano Zeta potential and sub micro particle Size Analyzer and confirmed with microscopy. The cytotoxicity of MWCNTs dispersed in different concentrations of T80 was evaluated in PANC1 (Human pancreatic cancer cell line) and Jurkat cell lines (Human T-cell lymphoblast cell …
