The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

open access: yesResponsive Materials, Volume 4, Issue 2, May 2026.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Retinal Pigment Epitheliopathy due to Sub‐Optimal Recycling of Vitamin A (RESORVA): A Novel RDH11 ‐Related Phenotype

open access: yesClinical Genetics, Volume 109, Issue 5, Page 972-977, May 2026.
RDH11 is a minor isoenzyme that catalyses the oxidation of 11‐cis‐retinol to 11‐cis‐retinal in the retinal pigment epithelium, alongside RDH5 and RDH10. Biallelic null variants in RDH11 lead to upregulation of RDH5 and RDH10 (transcriptional adaptation), maintaining 11‐cis‐retinal bioavailability, but still causing Retinal Pigment Epitheliopathy due to

Optical Behavior of an Enhanced Monofocal Intraocular Lens Compared with a Standard One

open access: yes, 2023
The aim of this work was to compare an enhanced monofocal (RayOne EMV RAO200E, Rayner) and standard monofocal (RayOne RAO600C Aspheric, Rayner) intraocular lenses (IOLs) for three nominal powers (+10.00 D, +20.00 D and +30.00 D) as a function of the ...
