Abstract Using photons to drive chemical reactions has become an increasingly important field of chemistry. Plasmonic materials can provide a means to introduce the energy necessary for nucleation and growth of nanoparticles by efficiently converting

Animals precisely control the morphology and assembly of guanine crystals to produce diverse optical phenomena but little is known about how organisms regulate crystallization to produce optically useful morphologies. Here, the authors demonstrate th

Phenol-soluble modulins (PSMs) are virulent peptides secreted by staphylococci that undergo self-assembly into amyloid fibrils. This study focuses on Staphylococcus aureus PSMα1 and PSMα3, which share homologous sequences but exhibit distinct amylo

Biomineralization is a process that takes place in all domains of life and which usually helps organisms to harden soft tissues by creating inorganic structures that facilitate their biological functions. It was shown that biominerals are under tight

Many animals undergo changes in functional colors during development, requiring the replacement of integument or pigment cells. A classic example of defensive color switching is found in hatchling lizards, which use conspicuous tail colors to deflect

Animals precisely control the morphology and assembly of highly reflective guanine crystals to produce diverse optical phenomena used in coloration and vision. However, little is known about how organisms regulate crystallization to produce optically

The ESCRT machinery mediate membrane remodeling in numerous processes in cells including cell division and nuclear membrane reformation. The identification of ESCRT homologs in Asgard archaea, currently considered the closest ancestor of eukaryotes,

Amyloid protein fibrils and some antimicrobial peptides (AMPs) share biophysical and structural properties. This observation suggests that ordered self-assembly can act as an AMP-regulating mechanism, and, vice versa, that human amyloids play a role

We report a new type of nanoparticle, consisting of a nucleic acid core (7500 nt) folded into a 35 nm DNA origami sphere, encapsulated by a capsid composed of all three SV40 virus capsid proteins. Compared to the prototype reported previously, whose

Many animals undergo dramatic changes in colour during development1,2. Changes in predation risk during ontogeny are associated with spectacular switches in defensive colours, typically involving the replacement of skin or the production of new pigme
