Single-molecule detection is the ultimate sensitivity in analytical chemistry and has been
largely unavailable in electrochemical analysis. Here, we demonstrate the feasibility of …

Recent high-bandwidth recordings of the oxidation and dissolution of 35 nm radius Ag
nanoparticles at a Au microelectrode show that these nanoparticles undergo multiple …

When a 10s–100s MHz frequency alternating current (ac) waveform is applied to a disk
ultramicroelectrode (UME) in an electrochemical cell, one achieves what is known as a hot …

Fast and cost-efficient detection and identification of bacteria in food and water samples and
biological fluids is an important challenge in bioanalytical chemistry. It was shown recently …

The detection of Rhamnolipid virulence factor produced by Pseudomonas aeruginosa
involved in nosocomial infections is reported by using the redox liposome single impact …

The collision events of single Lactococcus lactis bacteria at Pt disk ultramicroelectrodes
(UMEs) were characterized using electrochemistry with correlated microscopy. A finite …

Investigating the collisions of individual metal nanoparticles (NPs) with electrodes can
provide new insights into their electrocatalytic behavior, mass transport, and interactions …

We report the electrodeposition of electrocatalytic clusters of platinum from femtomolar
platinate solutions. An inert carbon fiber ultramicroelectrode (UME) was held at a potential …

The adsorption events and movements of individual E. coli and B. subtilis bacteria were
detected in real time using ultramicroelectrodes (UMEs). Electrochemical detection of single …
