Journal of Raman Spectroscopy, EarlyView.We investigate tip‐induced bond weakening of a single alkyne center immobilized and aligned upright on Au(111) using a rigid triphenylmethane‐based tripod. By varying the tip–molecule distance, we observe shifts in the ≡C–H and –C≡C– vibrational bands via ultrahigh vacuum low‐temperature tip‐enhanced Raman scattering (TERS).

Macromolecular Rapid Communications, EarlyView.Linear polyglycerol is proposed as a PEG‐alternative in mRNA‐loaded lipid nanoparticles to limit activation of anti‐PEG antibodies and reduce immunogenicity. Resulting nanoparticles may provide similar gene delivery capabilities, while preventing binding of anti‐PEG antibodies compared to PEGylated counterparts.

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research
Mass Spectrometry Reviews, EarlyView.ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

Mass Spectrometry Reviews, EarlyView.ABSTRACT Phytocannabinoids are bioactive metabolites derived from the Cannabis sativa plant. They have garnered attention due to their recreational uses and therapeutic potential. Although various analytical strategies have been employed for their analysis, mass spectrometry (MS) coupled to chromatographic separation is superior due to its sensitivity ...

Movement Disorders, EarlyView.Abstract Background Membrane contact sites are crucial for the exchange of ions or lipids and thus are critical for the function and maintenance of organelles. VPS13A is a membrane‐residing, bridge‐like protein connecting two membranes to enable bulk lipid transfer. Loss‐of‐function mutations in the VPS13A gene cause VPS13A disease.

A Rapid and Sensitive Method for the Determination of Chitosan Concentration by NMR Relaxometry
Magnetic Resonance in Chemistry, EarlyView.ABSTRACT A rapid, reagent‐free method for the quantification of chitosan in aqueous solutions was developed using 1H nuclear magnetic resonance (NMR) relaxometry. Transverse relaxation times (T2) of chitosan solutions (5–1000 mg/L) were measured with a Carr–Purcell–Meiboom–Gill (CPMG) sequence on a benchtop NMR relaxometer.
