New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids

open access: yesJournal of Applied Toxicology, Volume 46, Issue 8, Page 2884-2894, August 2026.
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Programmable Inter‐Droplet Communication by Polymer‐Gated Ion Transport Through Nanopore Lattices

open access: yesSmall Science, Volume 6, Issue 8, August 2026.
Laser‐written polyelectrolyte barriers were applied for regulating imbibition and ion transport through silica mesopores between droplet compartments. Specific imbibition sequences and precipitation readouts indicated cation‐selective transport across the barriers. Depending on salt identity, barrier, and experimental parameters, ionic transport ranged

Positive and negative regulation of carbon nanotube catalysts through encapsulation within macrocycles

open access: yesNature Communications, 2018
Doping carbon nanomaterials with heteroatoms is the most common way to change their catalytic activity. Here, the authors show that the catalytic properties of single-walled carbon nanotubes can be modified by non-covalently encapsulating them within ...
