Evaporation and Discharge Dynamics of Highly Charged Multicomponent Droplets Generated by Electrospray Ionization [PDF]

, 2010
We investigate the Rayleigh discharge and evaporation dynamics of highly charged two-component droplets consisting principally of methanol with 2-methoxyethanol, tert-butanol, or m-nitrobenzyl alcohol.

Ternary Thermosensitive Hydrogel‐Encapsulated Macrolactam Heneicosapeptide Eliminates Epidermal Multidrug‐Resistant Bi‐Microbial Colonization

Advanced Functional Materials, EarlyView.
The co‐existence of Gram‐negative Pseudomonas aeruginosa and Gram‐positive Staphylococcus aureus superbugs in open wounds exacerbates the difficulty of rational treatments. This study develops a hydrogel comprised of poloxamer, hyaluronic acid, and a de novo designed antimicrobial cyclic peptide.

Time‐resolved multiparameter analytics on a cell‐free production platform for acyl‐CoA precursors

Analytical Science Advances, Volume 3, Issue 11-12, Page 289-296, December 2022., 2022
Abstract Cell‐free biosynthesis is emerging as a very attractive alternative for the production of market‐relevant molecules. The free combination of enzymes, regardless of where they are isolated from, raises the possibility to build more efficient synthetic routes but at the same time leads to higher complexity regarding the analysis of the different

Structural study of analogues of Titan s haze by trapped ion mobility coupled with a Fourier transform ion cyclotron mass spectrometer [PDF]

, 2019
The aerosols present in the atmosphere of the Saturn s moon Titan are of particular planetary science interest and several spacecraft missions already allowed to gather spectroscopic data. Titan haze s analogs, so-called tholins, were produced on earth to push forward the comprehension of their formation and properties.

Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

Advanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Atmospheric Pressure Mass Spectrometry of Single Viruses and Nanoparticles by Nanoelectromechanical Systems [PDF]

arXiv, 2020
Mass spectrometry of intact nanoparticles and viruses can serve as a potent characterization tool for material science and biophysics. Inaccessible by widespread commercial techniques, the mass of single nanoparticles and viruses (>10MDa) can be readily measured by NEMS (Nanoelectromechanical Systems) based Mass Spectrometry, where charged and isolated

Toward Personalized Stationary Chromatography Phases: Equipping Commercial Silica Phases with Selected Peptide‐Based Binding Domains to Tailor Affinity

Advanced Materials Interfaces, EarlyView.
The 7‐mer peptide motifs QFFLFFQ, QFFEFFQ, and QFQQSFF, known as good, medium, and poor binders for the photosensitizers m‐THPC and Chlorin E6 are covalently immobilized on commercial amino‐functionalized silica particles by inverse electron‐demand Diels‐Alder ligation.

Shotgun lipidomics of cardiolipin molecular species in lipid extracts of biological samples

Journal of Lipid Research, 2006
Cardiolipin is a prominent component of the mitochondrial inner membranes contributing to the regulation of multiple discrete mitochondrial functions. Here, we extend shotgun lipidomics to identify and quantitate cardiolipin molecular species directly ...
