Engineering Concentration‐Dependent Intravitreal Mobility via Cyclic Arginine‐Enriched Nanocarrier Surface Modification: In Vivo Proof‐of‐Concept in a Porcine Large Animal Model

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...

Oxygels: Tunable Phosphorescent Hydrogels for Cherenkov‐Excited Luminescence Imaging (CELI) of Oxygen

open access: yesAdvanced Healthcare Materials, EarlyView.
Biocompatible hydrogels with covalently embedded near‐infrared phosphorescent probes enable local tissue pO2 quantification by means of Cherenkov‐excited luminescence imaging (CELI), where optical excitation occurs within tissues upon irradiation with high‐energy electron beams.

Aging and the cornea [PDF]

open access: yesBritish Journal of Ophthalmology, 1997
Aging, the persistent decline in age specific fitness of an organism as a result of internal physiological deterioration, is a common process among multicellular organisms.1 In humans, aging is usually monitored in relation to time, which renders it difficult to differentiate between time dependent biological changes and damage from environmental ...

Silicone Breast Implants as a Model System for Understanding Polymer Permeation in Soft Materials In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
Silicone breast implants are presented as a model system for understanding polymer permeation in vivo. Rather than representing material failure, “gel bleed” emerges from solution–diffusion transport‐mediated. By integrating polymer architecture, physicochemical transport, and biointerfacial processes, this review provides a unified framework that ...
