distribution of these nanoparticles using a Scanning Mobility Particle Spectrometer. We designed a nanoparticle collection cell to collect the nanoparticles efficiently, analyzed the nanoparticles for shape and size using Tunneling Electron Microscopy (TEM...
Identification and characterization of M cells in the mammalian conjunctiva
(University of Missouri--Columbia, 2007)
the hypothesis that the Guinea pig conjunctival FAE contains an antigen-sampling M cell. A cell with typical M-cell characteristics was identified in the conjunctival FAE using a variety of microscopy techniques. These putative M cells selectively bound...
In situ polymerizing collagen for the development of 3D printed tissue engineering scaffolds
(University of Missouri--Columbia, 2018)
-inflammatory compounds such as gold nanoparticles and curcumin were also incorporated into the scaffolds post printing in order to further tailor the cellular responses to the scaffolds. Scanning electron microscopy and neutron activation analysis were performed...
Development of a flexible image-based approach for studying signal transduction in isolated arterioles
(University of Missouri--Columbia, 2007)
Myogenic constriction in arterioles occurs when membrane tension leads to smooth muscle depolarization and voltage-gated calcium channel activation. A barrier to understanding the exact signaling events is the limited ...
Self-assembled peptide nanostructures for electrical, optical, and magnetic applications
(University of Missouri--Columbia, 2018)
in the self-assembly process of FF is explored by combining density functional theory (DFT) along with experimental characterization techniques such as electron microscopy, Raman scattering, and x-ray diffraction (XRD). One of the objectives of this work...
Development of a novel antimicrobial food packaging film containing silver nanoparticles
(University of Missouri--Columbia, 2018)
NP/PVA/BNC film. The flexibility of BNC was greatly improved by mixing with 3% PVA solution. The films exhibited good mechanical property and higher oxygen barrier capacity. The results of scanning electron microscopy (SEM) showed the surface structure...
Enhancing methanol electro-oxidation by double oxide incorporation with platinum on carbon nanotubes
(University of Missouri--Columbia, 2016)
Electro-oxidation of methanol was investigated on platinum catalyst supported on a double oxide nanocomposite support of tin oxide and carbon-doped titanium dioxide. The Pt-SnO2-C-/CNTs electro catalyst demonstrated about ...
Large-scale fabrication of SiC nanofibers and plasma interface engineering of polymer nanocomposites and dental composite restoration
(University of Missouri--Columbia, 2010)
was attributed to enhanced dispersion and interfacial adhesion observed visually and by electron microscopy. A non-thermal argon plasma brush treatment increased the micro-tensile strength of dental composite restorations. FTIR observed an increase in carbonyl...
Cryo-EM reveals how adeno-associated virus engages its receptor AAVR and an investigation of the GPR108 ectodomain
(University of Missouri--Columbia, 2022)
of AAVR was not revealed in our previous structure, although it had been shown to be involved in cellular entry for many AAV serotypes, including AAV2. Utilizing cryogenic electron microscopy (cryo-EM) we explore the AAV5-AAVR interactions, using an AAV5...
Peptide Amphiphile micelles (pams)-biomolecular materials capeble of modulating the immune system
