In-situ Raman spectroscopy of amorphous calcium phosphate to crystalline hydroxyapatite transformation

MethodsX, 2018
Amorphous calcium phosphate (Ca3(PO4)2xnH2O; n = 3–4.5; ACP) is a precursor phase of the mineral hydroxyapatite (Ca5(PO4)3(OH); HAP) that in natural settings occurs during both authigenic and biogenic mineral formation.

Oil‐Coated Nanoplastics Induce Rapid Membrane Disruption and Severe Intestinal Injury

Advanced Science, EarlyView.
Oil‐rich food contact dramatically amplifies MNP release from plastic takeout containers, producing oil‐coated nanoplastics with altered surface properties and rapid membrane‐disruptive effects. These particles cause severe intestinal barrier damage and immune dysfunction in mice, and risk modeling suggests that long‐term gastrointestinal burdens may ...

An ATP‐Mediated Antibiotic β‐Peptide Nanofiber That Kills Multidrug‐Resistant Bacteria via a Multistage Mechanism

Advanced Science, EarlyView.
The 3K‐AP system forms infinite supramolecular fibrils that undergo controlled degradation into shorter fragments upon enzymatic hydrolysis. Multitechnique imaging reveals a stepwise bacteriolytic mechanism involving bacterial entrapment, disassembly into lethal constructs, and associated extracellular vesicle release, highlighting the dynamic ...
