The Affinity of Melanin for Chloroquine*
Journal of Investigative Dermatology, 1965 The localization of chloroquine in areas of melanin pigmentation has recently been established. Zvaifler and his co-workers (1) found that the concentration of this drug in the eyes of pigmented rats paralleled the degree of melanin pigmentation. In addition, they noted that chloroquine persists at high levels in the iris and choroid for at least 28 ...

Designing Physical Unclonable Functions From Optically Active Materials
Advanced Materials, EarlyView.Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Active Biopaste for Coral Reef Restoration
Advanced Materials, EarlyView.Preserving coral reefs is essential. A conductive, hardening paste for coral attachment and mineral accretion technology is developed, using a bio‐based acrylate soybean oil matrix and graphene nanoplatelets. Corals are attached with and onto the conductive paste, electricity is applied, water electrolysis is induced, and calcium is deposited at the ...
