Increasing the Membrane Permeability of a Fern with DMSO
Bio-Protocol, 2018 Cell membrane prevents the entrance of extra molecules (e.g., transcription and translation inhibitors) into the cell. For studying the physiological effects of transcription and translation inhibitors on Hymenophyllum caudiculatum fronds, we incubate ...

Analysis of Antimicrobial-Triggered Membrane Depolarisation Using Voltage Sensitive Dyes
Frontiers in Cell and Developmental Biology, 2016 The bacterial cytoplasmic membrane is a major inhibitory target for antimicrobial compounds. Commonly, although not exclusively, these compounds unfold their antimicrobial activity by disrupting the essential barrier function of the cell membrane.

Permeability of a Cell Membrane Junction [PDF]
The Journal of General Physiology, 1969 The ion permeability of the membrane junctions between Chironomus salivary gland cells is strongly depressed by treatments that are generally known to inhibit energy metabolism. These treatments include prolonged cooling at 6°–8°C, and exposure to dinitrophenol, cyanide, oligomycin, and N-ethylmaleimide.

Important factors for cell-membrane permeabilization by gold nanoparticles activated by nanosecond-laser irradiation [PDF]
Int J Nanomedicine. 2017 Aug 7;12:5659-5672, 2018 Purpose: Pulsed-laser irradiation of light-absorbing gold nanoparticles (AuNPs) attached to cells transiently increases cell membrane permeability for targeted molecule delivery. Here, we targeted EGFR on the ovarian carcinoma cell line OVCAR-3 with AuNPs.

On the possible mechanisms of the selective effect of a non-equilibrium plasma on healthy and cancer cells in a physiological solution [PDF]
Plasma Res. Express 1 (2019) 045001, 2019 This paper discusses possible mechanisms for the selective effect of weakly ionized non-equilibrium plasma and currents in electrolyte on healthy and cancerous cells in physiological saline in a Petri dish. The interaction with the plasma source leads to a change in osmotic pressure, which affects the electro-mechanical properties of cell membranes in ...

Data-driven equation for drug-membrane permeability across drugs and membranes [PDF]
The Journal of Chemical Physics 154, 244114 (2021), 2020 Drug efficacy depends on its capacity to permeate across the cell membrane. We consider the prediction of passive drug-membrane permeability coefficients. Beyond the widely recognized correlation with hydrophobicity, we additionally consider the functional relationship between passive permeation and acidity.

Sharp, localized phase transitions in single neuronal cells [PDF]
published in PNAS 2022, 2022 The origin of nonlinear responses in cells has been suggested to be crucial for various cell functions including the propagation of the nervous impulse. In physics nonlinear behavior often originates from phase transitions. Evidence for such transitions on the single cell level, however, has so far not been provided leaving the field unattended by the ...
