Nanoformulation For Anticancer Drug Delivery: Enhanced Pharmacokinetics And Circulation, Gaurav Parekh
Nanoformulation For Anticancer Drug Delivery: Enhanced Pharmacokinetics And Circulation, Gaurav Parekh
Doctoral Dissertations
In this study, we have explored the application of the Layer-by-Layer (LbL) assembly technique for improving injectable drug delivery systems of low soluble anticancer drugs (e.g. Camptothecin (CPT), Paclitaxel (PTX) or Doxorubicin (DOX)). For this study, a polyelectrolyte shell encapsulates different types of drug nanocores (e.g. soft core, nanomicelle or solid lipid nanocores).The low soluble drugs tend to crystallize and precipitate in an aqueous medium. This is the reason they cannot be injected and may have low concentrations and low circulation time in the blood. Even though these drugs when present in the cancer microenvironment have high anti-tumor inhibition, the …
Surface Modification Of Noble Metal Nanostructures Toward Biomedical Applications, Samir V. Jenkins
Surface Modification Of Noble Metal Nanostructures Toward Biomedical Applications, Samir V. Jenkins
Graduate Theses and Dissertations
Noble metal nanostructures have seen a steady increase in biomedical application over the last several decades; new diagnostic and therapeutic modalities are under intense investigation. Many of these applications are possible because of post-synthetic modifications to the particle surface. These modifications take a variety of forms and can significantly affect the pharmacokinetics of these particles. In this work, various surface modifications were investigated. Particle agglomeration, which occurs when particle surfaces remain in contact, can significantly affect the toxicity and efficacy of a nanomedicine. Darkfield microscopy and single-particle ICP-MS were developed as complementary methods to detect agglomeration in blood, with the …
Improving Practices In Nanomedicine Through Near Real-Time Pharmacokinetic Analysis, Isidro B. Magana
Improving Practices In Nanomedicine Through Near Real-Time Pharmacokinetic Analysis, Isidro B. Magana
Doctoral Dissertations
More than a decade into the development of gold nanoparticles, with multiple clinical trials underway, ongoing pre-clinical research continues towards better understanding in vivo interactions. The goal is treatment optimization through improved best practices. In an effort to collect information for healthcare providers enabling informed decisions in a relevant time frame, instrumentation for real-time plasma concentration (multi-wavelength photoplethysmography) and protocols for rapid elemental analysis (energy dispersive X-Ray fluorescence) of biopsied tumor tissue have been developed in a murine model. An initial analysis, designed to demonstrate the robust nature and utility of the techniques, revealed that area under the bioavailability curve …
Creation Of A 3d Construct To Aid Cell Migration And Promote Cell Capture, Joseph Michael Sanders
Creation Of A 3d Construct To Aid Cell Migration And Promote Cell Capture, Joseph Michael Sanders
Legacy Theses & Dissertations (2009 - 2024)
Most cancer-related deaths are attributed to metastasis. The tumor microenvironment is a complex environment which is not fully understood. The Nano Intravital Device (NANIVID) is a versatile, biocompatible device that allows for the manipulation of the tumor microenvironment in vitro and in vivo, providing a platform to study various aspects of tumor progression. The purpose of this study is to modify the NANIVID to resemble the tumor microenvironment in order to allow for a seamless transition from the in vivo environment into the engineered environment within the NANIVID. This engineered microenvironment will promote cell migration and cell capture. It has …
