Targeting hMSC Response via Surface Carbonyl Groups, Contact Angle, and Protein Interactions

March 1, 2019
Author(s)
Max J. Lerman, Shinichiro Muramoto, Navein Arumugasaamy, Michael Van Order, Josephine Lembong, Anushka Gerald, John G. Gillen, John P. Fisher
Traditional 2D culture systems made of polystyrene (PS) require the addition of surface chemistry beyond the nominal phenyl groups present to facilitate and encourage cell adhesion. Determining the surface properties which enhance protein adhesion from

The Evolution of Polystyrene as a Cell Culture Material: A Brief History

April 10, 2018

Max J. Lerman, Josephine Lembong, Shinichiro Muramoto, John G. Gillen, John P. Fisher
Polystyrene (PS) has brought in vitro cell culture from its humble beginnings to the modern era, propelling dozens of research fields along the way. This review discusses the development of the material, fabrication, and treatment approaches to create the

PEGylation of zinc nanoparticles amplifies their ability to enhance olfactory responses to odorant

December 20, 2017

Melissa Singletary, Samantha Hagerty, Shinichiro Muramoto, Yasmine Daniels, William A. MacCrehan, Gheorghe Stan, June W. Lau, Oleg Pustovyy, Ludmila Globa, Edward E. Morrison, Iryna Sorokulova, Vitaly Vodyanoy
Responses of olfactory sensory neurons to odorants are intensely enhanced with the addition of small endogenous and engineered zinc nanoparticles, as shown by physiological experiments. The highest enhancement was recorded with 1.2 nm non-oxidized zinc

After oxidation, zinc nanoparticles lose their ability to enhance responses to odorants

September 20, 2016

Samantha Hagerty, Yasmine C. Daniels, Melissa Singletary, Oleg Pustovyy, Ludmila Globa, William A. MacCrehan, Shinichiro Muramoto, June W. Lau, Edward Morrison, Iryna Sorokulova, Vitaly Vodyanoy, Gheorghe Stan
Electrical responses of olfactory sensory neurons to odorants were examined in the presence of zinc nanoparticles of various sizes and degrees of oxidation. The zinc nanoparticles were prepared by the underwater electrical discharge method and analyzed by

Ultraviolet/Ozone as a tool to control grafting density in surface-initiated controlled-radical polymerizations via ablation of bromine

July 21, 2016

Richard J. Sheridan, Sara V. Orski, Shinichiro Muramoto, Christopher M. Stafford, Kathryn L. Beers
We used an ultraviolet-ozone (UVO) cleaner to create substrates for atom-transfer radical polymerization (ATRP) with varying surface initiator coverage. We collected complementary time-of-flight secondary ion mass spectrometry (ToF-SIMS) and X-ray

Engineered metal nanoparticles in the sub-nanomolar levels kill cancer cells

April 18, 2016

Yasmine C. Daniels, William A. MacCrehan, Shinichiro Muramoto, Gheorghe NMN Stan, Vitaly Vodyanoy, Oleg Pustovyy
Zinc and copper metal nanoparticles were produced from bulk metal rods by an underwater high-voltage discharge method. The metal nanoparticles, with estimated diameters of 1 nm to 2 nm, were determined to be more than 85 % non-oxidized. Exposure of rat RG2

Vapor-Liquid-Solid Etch of Semiconductor Surface Channels by Running Gold Nanodroplets

We show that Au nanoparticles spontaneously move across the (001) surface of InP, InAs, and GaP when heated in the presence of water vapor. As they move, the particles etch crystallographically aligned grooves into the surface. We show that this process is

Increased carrier mobility and lifetime in CdSe quantum dot thin films through surface passivation and doping

November 4, 2015

Daniel Straus, E. D. Goodwin, E. A. Gaulding, Shinichiro Muramoto, Murray B. Christopher, Cherie R. Kagan
Passivating surface defects and controlling the carrier concentration and mobility in quantum dot (QD) thin films is a prerequisite to designing electronic and optoelectronic devices. We investigate the effect of introducing indium in CdSe QD thin films on
