DOI: 10.1002/adfm.202004068
Abstract: It is shown that Gram‐type differentiation, an essential tool in microbiology, can now be easily accomplished by using the chain‐elongated conjugated oligoelectrolyte COE‐S6. Specifically, COE‐S6 can be used as a fluorescent membrane probe that distinguishes… read more here.

How bacterial cell division might cheat turgor pressure – a unified mechanism of septal division in Gram‐positive and Gram‐negative bacteria
Sign Up to like & getrecommendations! Published in 2017 at "BioEssays"
DOI: 10.1002/bies.201700045
Abstract: An important question for bacterial cell division is how the invaginating septum can overcome the turgor force generated by the high osmolarity of the cytoplasm. I suggest that it may not need to. Several studies… read more here.

Semisynthetic Vitamin E Derivatives as Potent Antibacterial Agents against Resistant Gram‐Positive Pathogens
Sign Up to like & getrecommendations! Published in 2020 at "ChemMedChem"
DOI: 10.1002/cmdc.202000792
Abstract: New 5‐substituted vitamin E derivatives were semisynthesized, and their antibacterial activity against human Gram‐positive and Gram‐negative pathogens was evaluated. Several vitamin E analogues were active against methicillin‐resistant Staphylococcus aureus (MRSA) and/or methicillin‐resistant Staphylococcus epidermidis (MRSE);… read more here.

DOI: 10.1002/jemt.24271
Abstract: Gram staining differentiates bacteria as gram‐positive and gram‐negative, depending on their cell wall constituents, and coloring cells in violet and pink, respectively. Sometimes, a subpopulation of the same bacterial species assumes different colors, ranging from… read more here.
