The retina represents a paradox, in that, while light and oxygen are essential for vision,
these conditions also favour the formation of reactive oxygen species leading to …

Melanins are ubiquitous biopolymers produced from phenols and catechols by oxidation.
They provide photoprotection, pigmentation and redox activity to most life forms, and inspire …

Analysis of the fluorescent spectra of chloroform-methanol extracts of human retinal pigment
epithelium confirmed the presence of lipofuscin pigments in the pigment epithelium of older …

Polydopamine (PDA) is a synthetic model for melanin and has a wide range of opto‐
electronic properties that underpin its utility in applied and biological settings, from …

The successful interfacing of electronics with biology is the next frontier for microelectronics
