A New Approach To The Development Of An Rsv Anti-Viral Targeted Nanocarrier For Dual Inhibition Of Viral Infection And Replication, Anthony N. Singer Jun 2018

A New Approach To The Development Of An Rsv Anti-Viral Targeted Nanocarrier For Dual Inhibition Of Viral Infection And Replication, Anthony N. Singer

Graduate Theses and Dissertations

Respiratory Syncytial Virus (RSV) is a potentially life-threatening respiratory pathogen that infects approximately 64 million children and immunocompromised adults globally per year. Currently, there is a need for prophylactic and therapeutic approaches effective against primary and secondary RSV infections. This project focuses on the development of a simple, smart, and scalable anti-RSV nanotherapeutic that combines novel cellular antiviral defense mechanisms targeting the inhibition of viral fusion and replication. An ICAM-1 targeted liposomal nanocarrier will be synthesized and coated with a layer of chitosan containing the anti-fusion HR2-D peptide as an extracellular defense mechanism. Additionally, chitosan complexed to dual expressing short ...


Macromolecular Soft Templates For Synthesis And Self-Assembly Of Functional Nanomaterials, Srikanth Nayak Jan 2018

Macromolecular Soft Templates For Synthesis And Self-Assembly Of Functional Nanomaterials, Srikanth Nayak

Graduate Theses and Dissertations

Nanostructured composite materials made of organic matrices and inorganic nanoparticles (NPs) represent the new paradigm of functional hybrid materials. This dissertation is focused on the synthesis and self-assembly of NPs within organic matrices which act as templates, targeting the formation of use-inspired structures. Particularly, self-assembly of macromolecules such as proteins and polymers, and polymer-functionalized NPs is utilized to create ordered assemblies of NPs. Inspired by the formation of chains of magnetic NPs in a group of bacteria referred to as Magnetotactic bacteria, we used Mms6, a biomineralization protein, as a template towards the formation of self-assembled arrays of magnetic NPs ...


Al/Ti Nanostructured Multilayers: From Mechanical, Tribological, To Corrosion Properties, Sina Izadi Apr 2016

Al/Ti Nanostructured Multilayers: From Mechanical, Tribological, To Corrosion Properties, Sina Izadi

Graduate Theses and Dissertations

Nanostructured metallic multilayers (NMMs) are well-known for their high strength in smaller bilayer thicknesses. Six Al/Ti (NMM) with different individual layer thickness were tested for their mechanical hardness using a nanoindentation tool. Individual layer thicknesses were chosen carefully to cover the whole confined layer slip (CLS) model. Nano-hardness had a reverse relation with the square root of individual layer thickness and reached a steady state at ~ 5 nm bilayer thickness. Decreasing the layer bilayer thickness from ~ 104 nm to ~ 5 nm, improved the mechanical hardness up to ~ 101%. Residual stresses were measured using grazing incident X-ray diffraction (GIXRD). Effect ...


Dynamic Self-Assembling Dna Nanosystems: Design And Engineering, Divita Mathur Jan 2016

Dynamic Self-Assembling Dna Nanosystems: Design And Engineering, Divita Mathur

Graduate Theses and Dissertations

Over the last thirty years, DNA has proven to be a great candidate for engineering nanoscale architectures. These DNA nanostructures have been applied in areas such as single-molecular analyses, nanopatterning, diagnostics and therapeutics. One of the most commonly-used techniques to engineer DNA-based two- and three-dimensional functional nanostructures is DNA origami, wherein a long single-stranded DNA (called scaffold) is folded into a predetermined shape with the help of a set of shorter oligonucleotides (called staples). This thesis discusses a brief overview of DNA nanotechnology (design, assembly and applications) and three primary projects undertaken in the area of dynamic self-assembling DNA nanosystems ...


Design Of Novel Nano-Carriers For Multi-Enzyme Co-Localization, Feng Jia Jan 2013

Design Of Novel Nano-Carriers For Multi-Enzyme Co-Localization, Feng Jia

Graduate Theses and Dissertations

The widely existing MECs in Nature have inspired researchers to design synthetic analogs to promote the overall catalytic efficiency in vitro by co-localizing multiple enzymes to mimic the MECs' unique functionalities. A number of efforts have been devoted to designing synthetic MECs in the past couples of decades. This thesis work has focused on developing novel strategies based on enzyme immobilization to design nano-carriers for multi-enzyme co-localization to realize kinetics enhancement and strong control of spatial arrangement of the enzymes. Three distinct approaches have been designed using different attachment methods and platforms.

First, the multifunctional polystyrene nanoparticles were designed for ...
