Calcification Potential of Intraocular Lenses (IOL). Predictive in vitro and in vivo models

Journal of Materials Science: Materials in Medicine
Opacification of intraocular lenses (IOLs) due to the formation of calcium phosphate occurs because of their contact with the aqueous humor (AH), which is supersaturated with respect to calcium phosphate.

Innovative Applications of Hydrogels in Contemporary Medicine

Gels
Hydrogels are hydrophilic, soft polymer networks with high water content and mechanical properties that are tunable; they are also biocompatible. Therefore, as biomaterials, they are of interest to modern medicine.

Large droplet release

Droplet, EarlyView.
Curved hydrophobic mesh surfaces enable stable release of large droplets exceeding the capillary length. By tuning surface curvature, porosity, and acceleration, oscillatory breakup is suppressed, producing near‐spherical droplets ideal for high‐precision fluid applications and multiphase flow control.

Molecular‐Level Modulation of Proton Transport via Electron‐Proton Coupling in Bio‐p‐n Junctions

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We developed a pH‐sensing device capable of operating in biological environments. A biohybrid p–n junction was constructed using bacteriorhodopsin (bR) and the photoconductive polymer poly(3‐hexylthiophene) (P3HT). Under light illumination, the photocurrent exhibits distinct transitions across various pH gradients, demonstrating the system's high ...

Tear pH: Hydrophilic lenses and the closed eye

, 1976
On a previous study of tear pH and the unfitted eye it was found that prolonged eye closure (i.e. overnight) resulted in a significant shift in the acid direction in 22 of the 23 patients measured.1 With the advent of continuous wear regimens, does the ...
