Real‐time quality and safety monitoring of fruit juice using paper‐based platform

open access: yesFood Biomacromolecules, EarlyView.
Schematic illustration of a paper‐based biosensor for rapid detection of fruit juice spoilage. Abstract Food spoilage and safety concerns still remain critically challenging within the fruit juice industry, especially as conventional detection methods, though precise, are often too time‐consuming, costly, and reliant on centralized laboratories.

Matrix Metalloproteinases in Periodontal and Peri‐Implant Diseases: Contribution to Their Pathogenesis, Diagnosis, and Treatment

open access: yesJournal of Periodontal Research, EarlyView.
This graphical abstract illustrates the role of matrix metalloproteinases (MMPs) across the pathogenesis, diagnosis, and therapeutics of periodontal and peri‐implant diseases. Microbial and host stimuli trigger MMP activation leading to extracellular matrix breakdown, point‐of‐care aMMP‐8 detection aids diagnosis, and adjunctive or AI‐assisted ...

Catalytic Amyloids: Turning Fibrils Into Biocatalysts

open access: yesChemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Amyloids, traditionally associated with diseases, have emerged as versatile catalytic scaffolds. From natural amyloid sequences to bioinspired and de novo designs, we highlight strategies to construct catalytic active sites and anchor enzymes onto fibrils, creating versatile nanomaterials with tunable activities. ABSTRACT Amyloids have been regarded as

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres

open access: yesAdvanced Functional Materials, Volume 36, Issue 19, 5 March 2026.
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...
