Synthetic Porous Melanin

Journal of the American Chemical Society, 2021
Commonly known as a skin pigment, melanin has a vital role in UV radiation protection, primarily acting as a radical scavenger. However, a lesser known natural property of melanin, observed in some melanized organisms, is its capacity to adsorb toxins, including metals and organic molecules.

Biomimetic Silica Microspheres in Biosensing

Molecules, 2010
Lipid vesicles spontaneously fuse and assemble into a lipid bilayer on planar or spherical silica surfaces and other substrates. The supported lipid bilayers (SLBs) maintain characteristics of biological membranes, and are thus considered to be ...

Porous and non-porous nanostructures

, 2013
Disclosed are a variety of porous and non-porous wire-like structures of microscopic and nanoscopic scale. For instance, disclosed are structures that comprise a porous object that comprises: (i) a first region; and (ii) a second region adjacent to the first region along an axis of the object, where the first region has at least one porous property ...

Porous emerald

ISSUE, 2016
Jago stirs: something is strange. Ice-cold wind streams from the aircon and relentless chatter from the radio: "…it would not be without reason to deem it a ghost or a phantom formed by the brain…"1 Reality blur: yes, he must have drifted off. Yes, the taxi, but no, why have we stopped? What time is it? He breathes in heavily through the nose.

PICALM::MLLT10 translocated leukemia

FEBS Letters, EarlyView.
This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
