Bioanalytical TERS and Advanced Data Processing Methods

Journal of Raman Spectroscopy, Volume 57, Issue 6, Page 977-994, June 2026.
Tip‐enhanced Raman spectroscopy delivers label‐free, subnanometer vibrational imaging of biological systems. Recent advances in instrumentation, data analysis, and ambient/liquid operation enable surface‐selective mapping of molecular heterogeneity in proteins, nucleic acids, membranes, and viruses, positioning TERS as a powerful platform for nanoscale

Meniscus‐Mediated Imaging of Soft Biological Membranes Using 200 kN/m Ultra‐Stiff 15 MHz MEMS AFM Probes

Journal of Molecular Recognition, Volume 39, Issue 3, May 2026.
ABSTRACT 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.

A Genome-Scale Atlas Reveals Complex Interplay of Transcription and Translation in an Archaeon

mSystems, 2023
The scale of post-transcriptional regulation and the implications of its interplay with other forms of regulation in environmental acclimation are underexplored for organisms of the domain Archaea.

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, Volume 73, Issue 2, Page 913-926, April 2026.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Identification of the D-glucuronyl C5-epimerase that introduces iduronic acid into N-linked glycans decorating archaeal glycoproteins

Communications Biology
In Halobacterium salinarum, halophilic archaea that grow in saturated salt solutions, glycoproteins are modified by an N-linked tetrasaccharide that includes iduronic acid (IdoA).

The protein interaction network of a taxis signal transduction system in a Halophilic Archaeon

BMC Microbiology, 2012
Background The taxis signaling system of the extreme halophilic archaeon Halobacterium (Hbt.) salinarum differs in several aspects from its model bacterial counterparts Escherichia coli and Bacillus subtilis.

Precise Capture of Membrane Proteins Using DNA‐Origami‐Constrained Nanodiscs

Small Structures, Volume 7, Issue 4, April 2026.
A designed DNA origami structure ensures manipulates and inserts an individual membrane protein in a single, captured nanodisc. Membrane proteins play a key role as cellular gatekeepers, regulating the flow of information and material across lipid membranes.

Phosphate-Dependent Behavior of the ArchaeonHalobacterium salinarumStrain R1 [PDF]

Journal of Bacteriology, 2009
ABSTRACTPhosphate is essential for life on earth, since it is an integral part of important biomolecules. The mechanisms applied by bacteria and eukarya to combat phosphate limitation are fairly well understood. However, it is not known how archaea sense phosphate limitation or which genes are regulated upon limitation.

Genomic and Ecological Flexibility Shape the Global Distribution of a Black Fungus

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Graphical abstract illustrating the integration of ecological and genomic data to explain the global adaptation of the black fungus Elasticomyces elasticus. ABSTRACT Black fungi are among the most stress‐resistant organisms known, yet the genetic and ecological foundations of their extraordinary resilience remain poorly understood.
