Self‐Sealing Microneedles Improve Precision and Reduce Reflux in Subretinal Cell Transplantation

Advanced Materials Technologies, EarlyView.
Ultrafine 49G microneedles enable subretinal delivery of induced pluripotent stem cell‐derived retinal pigment epithelial cells through a 50 µm outer diameter tip. Compared with conventional 38G microcannulas, these microneedles reduce cell suspension reflux in a rabbit model, highlighting the potential of microinvasive delivery instruments to improve ...

Helicity‐Dependent All‐Optical Switching in Bi,Ga‐Substituted Rare‐Earth Iron Garnet Films Driven by Orbital Magnetic Moment

Advanced Optical Materials, EarlyView.
Helicity‐dependent all‐optical magnetization switching was demonstrated for the Bi‐ and Ga‐substituted rare‐earth (R) iron garnet crystal thin films (Bi,Ga:RIG; R = Eu3+, Nd3+, and Y3+). The efficiency followed the order EIG > NIG > YIG. These results show the correlation between 4f orbital moment (4f〈L〉) of R3+ and helicity‐dependent optical ...

Combination of 0.09% cyclosporine and intense pulsed light (IPL) therapy for the treatment of dry eye disease in symptomatic contact lens wearers: study protocol for a sham-controlled randomized clinical trial

Trials
Background Discomfort while using soft contact lenses is a major concern in eyecare, and it is strongly linked to dry eye. Many new dry eye therapies have not yet been studied on contact lens users.

Hydrophobic Silicon Quantum Dots for Potential Imaging of Tear Film Lipid Layer

Nanomaterials
The tear film, consisting of the aqueous and lipid layers, maintains the homeostasis of the ocular surface; therefore, when disturbed, it can cause dry eye, which affects millions of people worldwide. Understanding the dynamics of the tear film layers is

Molecular Appendix Adjusted Architectural Propagations of Red‐Light Controlled Macroscopic Photoactuating Performances

Advanced Robotics Research, EarlyView.
Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction

Adverse effects of meteorological factors and air pollutants on dry eye disease: a hospital-based retrospective cohort study

Scientific Reports
Although previous studies have suggested that meteorological factors and air pollutants can cause dry eye disease (DED), few clinical cohort studies have determined the individual and combined effects of these factors on DED.

Comparative study of the therapeutic effects of different medications on DM-associated dry eye syndrome after vitrectomy

Frontiers in Medicine
No prior studies have compared ciclosporin (CsA) and sodium hyaluronate (SH) eye drops for treating diabetes mellitus-associated dry eye syndrome (DMDES) after vitrectomy.

A Multidirectional Textile Interface for Remote Control Using Dynamic Area‐Based Capacitance Modulation

Advanced Robotics Research, EarlyView.
Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...
