41. Nanoscopic Porous Sensors
John J Kasianowicz, Joseph William Robertson, Elaine Chan, Joseph Earl Reiner, Vincent M Stanford
There are thousands of different nanometer-scale pores in biology,many of which act as sensors for specific chemical agents. Recent work suggests that protein and solid-state nanopores have many potential uses in a wide variety of analytical applicat ...
42. Single molecule measurements within individual membrane-bound ion channels using a polymer-based bilayer lipid membrane chip
Louis P Hromada, Brian Joseph Nablo, Michael Gaitan, John J Kasianowicz, Don DeVoe
A polymer microfluidic platform for electrophysiological ion channel measurements is presented. The system includes an open-well bilayer lipid membrane formation site, integrated Ag/AgCl reference electrodes for on-chip electrical measurements, and m ...
43. Competitive Adsorption of Thiolated Polyethylene Glycol and Mercaptoproprionic acid on Gold Nanoparticles Measured by Physical Characterization Methods
De-Hao D. Tsai, Frank W DelRio, Robert I. MacCuspie, Tae Joon Cho, Michael Russel Zachariah, Vincent A Hackley
Adsorption kinetics between thiolated polyethylene glycol (SH-PEG) and mercaptoproprionic acid (MPA) on gold nanoparticles (Au-NP) were studied using dynamic light scattering (DLS) and electrospray differential mobility analysis (ES-DMA). Through a c ...
