Electrical Impedance Spectroscopy with Bacterial Biofilms: Neuronal-like Behavior. [PDF]
Nano Lett, 2023 AbstractNegative capacitance at low frequencies for neurons was first demonstrated in 1941 (Kenneth S. Cole) using extracellular electrodes. The phenomenon subsequently was explained by Cole using the Hodgkin-Huxley model and is due to the activity of voltage-gated potassium ion channels. We show thatE.

Electrical impedance spectroscopy detects skin barrier dysfunction in childhood atopic dermatitis
Allergy. European Journal of Allergy and Clinical Immunology, 2023 Skin barrier dysfunction is associated with the development of atopic dermatitis (AD), however methods to assess skin barrier function are limited. We investigated the use of electrical impedance spectroscopy (EIS) to detect skin barrier dysfunction in ...
