Droplet actuation in PPy redox process

Tsai Y-T, Choi C-H, Yang E.H., Stevens Institute of Technology, US

A wettability switchable surface will be demonstrated to study the contact angle hysteresis of liquid droplet. Manipulation of surface wettability can be applied in the field of biomedical (cell-surface interaction) and fluids dynamics (friction reduction). [...]

Nanoscale Graphene Lithography Using an Atomic Force Microscope

Kumar K., Yang E.H., Stevens Institute of Technology, US

In this work, we study Atomic Force Microscope local oxidation lithography to precisely fabricate nanometer-scale structures from graphene, a recently discovered material with exceptional electrical properties. We have systematically studied oxidation parameters (electric field, humidity, [...]

Extraction of Bulk Material Properties from Phonon Dispersion Spectra

Kumar N., Pochiraju K., Stevens Institute of Technology, US

Experimental characterization of mechanical behavior of nanostructures can be cumbersome and expensive. Design of nano-structured materials with properties tailored to meet macro-scale requirements invariably requires model-based understanding of the structure-to -property relationships. In this effort, [...]

5-aminolevulinic Acid Conjugated Gold Nanoparticles for Cancer Treatment

Khaing Oo M.K., Yang X., Wang H., Du H., Stevens Institute of Technology, US

To improve 5- aminolevulinic acid’s (5-ALA) selective retention in tumor cells and efficient damage tumor cells in photodynamic therapy (PDT), biocompatible gold (Au) nanoparticles were proposed as the carrier to selectively deliver 5-ALA into tumor-like [...]

Preparation of multifuctional nanofibrous scaffold for tissue engineering

Yang X., Ogbolu K.R., Wang H., Stevens Institute of Technology, US

Multifucntional fibrous scaffolds can be produced via layer-by-layer deposition of electrospun nanofibers containing variable function. This scaffolds can be used in tissue engineering of complex structure by allowing specific controlled microenvironment for heterogeneous cell types.
