Enhanced performance of all organic field-effect transistors and capacitors through choice of solvent

Guha S., Knotts G., Ukah N.B., University of Missouri, US

We demonstrate low-operating voltage, high mobility, and stable organic field-effect transistors (OFETs) using both non-polar and polar polymeric dielectrics such as poly(4-vinyl phenol) (PVP), poly methyl metacrylate (PMMA), and polyvinylidene fluoride-trifluoroethylene (PVDF-TrFe), dissolved in solvents [...]

Cellular uptake and cytotoxic effect of broccoli phytochemical based gold nanoparticles (B-AuNPs): Enhanced cancer therapeutic efficacy

Khoobchandani M., Katti K., Katti K.V., Zambre A., Katti K., Katti K.V., University of Missouri, US

The interaction phytochemicals from Broccoli with gold salt results in dual reduction and surface capping to produce well-defined stable and biocompatible gold nanoparticles. The core sizes of B-AuNPs are in the range of 10–20 nm [...]

A Novel Microscale Coulter Counter for Cell Monitoring and Detection

Wu Y., Critser J., Almasri M., University of Missouri, US

A MEMS based Coulter counter for cell detection and monitoring is designed, fabricated and characterized. The novelty of this design is the use of mixing, focusing and detection on a single chip as well as [...]

Flexible Micropost Arrays For Studying Traction Forces Of Vascular Smooth Muscle Cells

Cheng Q., Sun Z., Meininger G.A., Almasri M., University of Missouri, US

This paper describes the design, modeling, fabrication and characterization of micromachined arrays of high density 3-dimensional microposts fabricated using flexible silicone elastomers for studying traction forces generated by vascular smooth muscle cell. It also reports [...]
