Advancing Tuberculosis Chemotherapy: Targeted Nanomedicines for the Mycobacterium TB Granuloma

Small, Volume 21, Issue 49, December 10, 2025.
This graphical abstract illustrates nanosystems used for targeted drug delivery into tuberculosis granulomas. It shows how targeting is influenced by size, pH, redox sensitivity, and surface charge. Various nanoparticles are incorporated with drugs to enhance penetration, stability, and release.

Nanodiamond‐Infused Microgels for pH‐Tunable Rheology, Lubrication, and UV Protection

Advanced Functional Materials, Volume 35, Issue 46, November 12, 2025.
Microgels consisting of swollen polyacrylic acid polymer networks, impregnated with nanodiamonds provide protection from ultraviolet (UV) radiation harmful to human health. Nanodiamonds enable UV blockage and control of the rheology (flow) and lubrication (skin‐feel) of these microgel‐skincare‐mimics.

Strong optical force acting on a dipolar particle over a multilayer substrate

, 2015
Optical forces acting on nano-sized particles are typically too small to be useful for particle manipulation. We theoretically and numerically demonstrate a mechanism that can significantly enhance the optical force acting on a small particle through a ...

Surface Enhanced Raman Scattering of a Lysosomal Fluorescent Dye

Analysis &Sensing, Volume 5, Issue 6, November 2025.
In this article, the interactions of a lysosomal fluorescent dye with gold nanoparticles are analyzed based on surface‐enhanced Raman scattering (SERS). Their dependence on changes in pH is related to their SERS spectra and to the SERS spectra of the aromatic fragments of the dye.

Toward Organic Mimics of Metallic Nanoparticles: Tuning and Enhancing Fluorescence in Binary Dye‐Based Nanoparticles

Chemistry – A European Journal, Volume 31, Issue 59, October 22, 2025.
Binary Fluorescent Organic Nanoparticles (вFONs) are made from two optically complementary polar and polarizable dyes (energy donor D and acceptor A). Core‐shell вFONs exhibit Nano Interfacial Emission Enhancement (NIEE), i.e. an enhanced fluorescence quantum yield and a blueshifted emission, compared to alloy вFONs of identical composition‐but devoid ...
