The current analytical techniques for characterizing printing and graphic arts substrates, particularly those used to date and to authenticate provenance, are largely ex situ and destructive. This limits the amount of data that can be captured from an

A Comparison of Ion Channel Current Blockades Caused by Individual Poly(ethylene glycol) Molecules and Polyoxometalate Nanoclusters

June 28, 2019
Author(s)
Haiyan Wang, John J. Kasianowicz, Joseph W. Robertson, Dianne L. Poster, Jessica Ettedgui
Proteinaceous nanometer-scale pores have been used to detect and physically characterize many different types of molecules at the single molecule limit. The method is based on the ability to measure the transient reduction in the ionic channel conductance
