Insights Into the Antibiofilm Activity of Carbon Quantum Dots Against a Panel of Different Microorganisms: A Review

open access: yesMicrobiologyOpen, Volume 15, Issue 5, October 2026.
Carbon quantum dots (CDs) have emerged as versatile nanoplatforms for combating biofilm‐associated infections through multiple mechanisms, including EPS disruption, membrane damage, ROS generation, and quorum sensing inhibition. This review highlights how CD physicochemical properties and surface engineering strategies influence antibiofilm activity ...

Photodegradation of Azo and Hydrazone Colourants on Cellulose‐Based Materials: A Mass Spectrometric Screening

open access: yesChemistrySelect, Volume 11, Issue 37, 6 October 2026.
Natural‐light ageing of early azo dyes and hydrazone pigments (AY36, AO7, and AR1) on cellulose‐based supports produces marked chromatic changes and distinct molecular transformations. LC–HRMS analysis of aged AY36 reveals degradation products associated with N‐oxidation, N‐dearylation, azo‐bond oxidation, and formaldehyde addition, providing a first ...

Naphthol and lens.

open access: yesIndian journal of medical sciences, 1992
Alpha and beta naphthols, the metabolites of naphthalene, a cataractogenic agent, was tested for it's effect on sheep lens proteases and their inhibitors. It reduced protease activities, not that of inhibitor activities of lens proteins. It also increased the efflux of free amino acid from lenses which was retarded by a high concentration of tissue ...

A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.
