Impedance biosensors are a class of electrical biosensors that show promise for point‐of‐
care and other applications due to low cost, ease of miniaturization, and label‐free …

Both clinical and analytical metrics produced by microarray-based assay technology have
recognized problems in reproducibility, reliability and analytical sensitivity. These issues are …

We have investigated the effect of the folding of DNA aptamers on the colloidal stability of
gold nanoparticles (AuNPs) to which an aptamer is tethered. On the basis of the studies of …

Surface hybridization reactions, in which sequence-specific recognition occurs between
immobilized and solution nucleic acids, are routinely carried out to quantify and interpret …

Electrochemical sensing of biomolecules eliminates the need for the bulky and expensive
optical instrumentation required in traditional fluorescence-based sensing assays …

In this paper, we study the charge dynamics in ionic polymer metal composites (IPMCs) in
response to a voltage difference applied across their electrodes. We use the Poisson …

Atoms, molecules, enzymes, proteins, DNAs, RNAs, nanoparticles, microparticles, tiles, and
bricks are some of the most commonly encountered building blocks in chemistry and …

Soft nanotechnology is a rapidly developing area of research that exploits principles such as
self-assembly, entropy, swelling and collapse transitions, and polymeric building blocks to …

Resistive pulse sensors, RPS, are allowing the transport mechanism of molecules, proteins
and even nanoparticles to be characterized as they traverse pores. Previous work using …

Adenosine triphosphate (ATP) aptamer has been widely used as a recognition unit for
biosensor development; however, its relatively poor specificity toward ATP against …
