Voltage-gated ion channels open and close in response to voltage changes across electrically excitable cell membranes. Voltage-gated potassium (Kv) channels are homotetramers with each subunit constructed from six transmembrane segments, S1-S6 (ref. 2). The voltage-sensing domain (segments S1-S4) contains charged...

Z-scan fluorescence correlation spectroscopy (FCS) is employed to characterize the interaction between arenicin-1 and supported lipid bilayers (SLBs) of different compositions. Lipid analogue C8-BODIPY 500/510C5-HPC and ATTO 465 labelled arenicin-1 are used to detect changes in lipid and peptide diffusion...

4-Nitro-1,8-naphthalic anhydride (NNA) was used to distinguish cysteine from homocysteine and other potentially interfering thiols through a novel sequential substitution mechanism. The discrimination involves a blue-fluorescent thioether formation via nucleophilic aromatic substitution of the nitro group by thiol, followed by...

Photo-induced switching of dyes into dark, long-lived states, such as a triplet state, has recently gained increasing interest, as a means to achieve ultra-high optical resolution. Additionally, these long lived states are often highly environment-sensitive and their photodynamics can thus...
