The essence of bionanotechnology lies in the application of nanotechnology/nanomaterials
to solve the biological problems. Quantum dots and nanoparticles hold potential biomedical …

Iron is an essential micronutrient, and, in the case of bacteria, its availability is commonly a
growth-limiting factor. However, correct functioning of cells requires that the labile pool of …

Ferritins, the cellular iron repositories, are self-assembled, hollow spherical nanocage
proteins composed of 24 subunits. The self-assembly process in ferritin generates the …

Bacterioferritin (Bfr) is a subfamily of ferritin protein family. Bfrs are composed of 24 identical
subunits and self-assemble into 4‐3-2-fold symmetric cage-like structure with the …

Oxo-bridged diiron proteins are a distinct class of non-heme iron proteins. Their active sites
are composed of two irons that are coordinated by amino acid side chains, and a bridging …

The self-assembled ferritin nanocages, nature's solution to iron toxicity and its low solubility,
scavenge free iron to synthesize hydrated ferric oxyhydroxide mineral inside their central …

Most pathogenic bacteria require iron for growth. However, this metal is not freely available
in the mammalian host. Due to its poor solubility and propensity to catalyze the generation of …

Antibiotic resistance is a global public health threat. The care of chronic infections is
complicated by bacterial biofilms. Biofilm embedded cells can be up to 1000-fold more …

Iron deficiency anaemia (IDA), the most widespread nutritional disorder, is a persistent
global health issue affecting millions, especially in resource-limited geographies. Oral iron …

Abstract The orthoquartzite Imawarì Yeuta cave hosts exceptional silica speleothems and
represents a unique model system to study the geomicrobiology associated to silica …
