Epithelia and endothelia delineate tissue compartments and control their environments by
regulating the passage of ions and solutes. This barrier function is essential for the …

The aim of this review is to discuss label-free and real-time assays characterizing the
electrical impedance of cells for biomedical and pharmacological applications. Electrical …

Conductive hydrogels, a class of novel polymeric material that combine the electronic
conductivity of intrinsically conductive materials and diverse functionalities of hydrogels, are …

A new impedimetric sensing strategy based on enzyme-triggered formation of enzyme-
tyramine concatamers on the nanogold-functionalized poly (amidoamine)(PAMAM) …

Therapies based on regenerative techniques have the potential to radically improve
healthcare in the coming years. As a result, there is an emerging need for non-destructive …

We aimed to study the time course decrease of human retinal pigment epithelium (RPE)
barrier function when exposed to blue light. To this end, we cultured ARPE-19 cells on …

Skin wound healing represents a critical medical topic. For its ideal case, the injured tissue
can repair quickly without scars. In this paper, an ECIS device was developed using nano …
