Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

Advanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

Transient twinkle perception is induced by sequential presentation of stimuli that flicker at frequencies above the critical fusion frequency

, 2015
The critical fusion frequency (CFF) is a threshold that represents the temporal limits of the human visual system. If two flickering stimuli with equal subjective luminances are presented simultaneously at different locations, the CFF is the temporal ...
