Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

open access: yesFEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.

Fluorescence correlation spectroscopy for the characterization of membranes : A short review [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2002
Fluorescence correlation spectroscopy (FCS) is a highly sensitive fluorescence microscopy technique that can be used to probe a wide range of biophysical processes including diffusion, Ligand-receptor binding and molecular aggregation on artificial and ...

A reversibly gated protein-transporting membrane channel made of DNA

open access: yesNature Communications, 2022
Artificial systems to control the transport of molecules across biomembranes can be useful for biosensing or drug delivery. Here, the authors assemble a DNA channel enabling the precisely timed, stimulus-controlled transport of functional proteins across

Quantitative Local Photosynthetic Flux Measurements at Isolated Chloroplasts and Thylakoid Membranes Using Scanning Electrochemical Microscopy (SECM) [PDF]

open access: yes, 2013
Scanning electrochemical microscopy (SECM) offers a fast and quantitative method to measure local fluxes within photosynthesis. In particular, we have measured the flux of oxygen and ferrocyanide (Fe(CN)64–), from the artificial electron acceptor ...

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Removal of adsorbing estrogenic micropollutants by nanofiltration membranes:Part B-Model development

open access: yes, 2013
Removal of estrone (E1) and estradiol (E2) by nanofiltration membranes at neutral pH is carried out both by size exclusion and adsorption. Size exclusion is dependent on the solute to pore radius ratio and the hormone-membrane affinity. It has been shown

Micromachined glass apertures for artificial lipid bilayer formation in a microfluidic system [PDF]

open access: yes, 1998
The use of spark assisted chemical engraving (SACE) to produce glass apertures that are suitable for the formation of artificial bilayer lipid membranes is described.

Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

open access: yesAdvanced Functional Materials, EarlyView.
Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

open access: yesAdvanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.
