MINFLUX nanoscopy: Visualising biological matter at the nanoscale level
Journal of Microscopy, Volume 298, Issue 2, Page 219-231, May 2025.Abstract Since its introduction in 2017, MINFLUX nanoscopy has shown that it can visualise fluorescent molecules with an exceptional localisation precision of a few nanometres. In this overview, we provide a brief insight into technical implementations, fluorescent marker developments and biological studies that have been conducted in connection with ...

Unveiling Unidirectional Transport within Janus Membranes
Small Structures, Volume 6, Issue 4, April 2025.GA: A three‐stage model is proposed to describe unidirectional transport through Janus membranes, encompassing liquid intrusion, capillary wetting, and liquid transport. The mechanisms of liquid intrusion include direct‐contact‐driven intrusion in bilayer structures and surface‐energy‐driven intrusion in gradient structures.

La membrana celular, que envuelve todas las células, establece los límites de la célula y preserva las diferencias fundamentales entre el interior de la misma y su medio. Esta membrana funciona como un filtro, muy selectivo, que regula la entrada de nutrientes y la salida de desechos, además de crear variaciones en la concentración de iones entre el ...

Andrology, Volume 13, Issue 2, Page 184-201, February 2025.Abstract Background Ion channels are essential for differentiation and maturation of germ cells, and even for fertilization in mammals. Different types of potassium channels have been identified, which are grouped into voltage‐gated channels (Kv), ligand‐gated channels (Kligand), inwardly rectifying channels (Kir), and tandem pore domain channels (K2P).
