Meniscus-Mediated Imaging of Soft Biological Membranes Using 200 kN/m Ultra-Stiff 15 MHz MEMS AFM Probes. [PDF]
J Mol RecognitABSTRACT Coronaviruses, among other membrane‐enveloped viruses, can remain infectious on surfaces in ambient air for days. Many bacteria and fungi also expose their plasma membranes to air environments. Key survival strategies in air include hydrophobic coatings to prevent water loss and waxy or silica‐based resistant cell walls.

The Effect of Bacterioruberin Deletion on Production of Bacteriorhodopsin in Halobacterium salinarum R1 [PDF]
Journal of Pure and Applied Chemistry Research, 2018 Bacteriorhodopsin is a retinal protein located in purple membrane of Halobacterium salinarum which acts as light-dependent proton pump. Bacterioruberin is a by-product in bacteriorhodopsin biosynthesis pathway in Halobacterium salinarum.

Protein Motifs for Proton Transfers That Build the Transmembrane Proton Gradient
Frontiers in Chemistry, 2021 Biological membranes are barriers to polar molecules, so membrane embedded proteins control the transfers between cellular compartments. Protein controlled transport moves substrates and activates cellular signaling cascades.

Three-dimensional view of ultrafast dynamics in photoexcited bacteriorhodopsin [PDF]
Nature Communications, 2019 Bacteriorhodopsin (bR) is a light-driven proton pump. The primary photochemical event upon light absorption is isomerization of the retinal chromophore.

Energy transfer from retinal to amino acids — a time-resolved study of the ultraviolet emission of bacteriorhodopsin [PDF]
, 1986 Two-step excitation of retinal in bacteriorhodopsin by visible light is followed by an energy transfer to amino acids that is seen as fluorescent emission around 350 nm.
