In situ Synthesis of Metal Selenide Nanoparticles by Selenium Nanoparticle Disproportionation Open
Amorphous Selenium Nanoparticles (α-SeNPs) exist in a metastable state of polymeric Se8 rings and Sen chains that break and reform by electron propagation. Here we show that this quality can underlie the formation of metal selenide nanopar…

Cloneable Selenium Nanoparticles As Multi-modal Bio-imaging Contrast Agents Open
A cloneable NanoParticle (cNP) is an inorganic nanoparticle that is synthesized by a protein. The protein determines the elemental composition, size, morphology, and other properties of the nanoparticle. Here, we describe the use of a clon…

Cloneable inorganic nanoparticles Open
When a defined protein/peptide (or combinations thereof) control and define the synthesis of an inorganic nanoparticle, the result is a cloneable NanoParticle (cNP).

A clonable selenium nanoparticle in action: high resolution localization of FtsZ using electron tomography Open
A meaningful understanding of biochemistry requires that we understand the function of proteins, which is heavily dependent on their structure and location within an organism. As the Resolution Revolution of cryo-electron microscopy gains …

Identification of a TeO32− reductase/mycothione reductase from<i>Rhodococcus erythropolis</i>PR4 Open
A Rhodococcus erythropolis bacterium that tolerates normally lethal concentrations of Fe(II), Cu(II), AsO32−, SeO32−, TeO32−, Cd(II) and Zn(II) was identified from an environmental isolate. In characterizing the molecular basis for metal t…

Metalloid Reductase Activity Modified by a Fused Se<sup>0</sup> Binding Peptide Open
A selenium nanoparticle binding peptide was isolated from a phage display library and genetically fused to a metalloid reductase that reduces selenite (SeO32-) to a Se0 nanoparticle (SeNP) form. The fusion of the Se binding peptide to the …

Enzyme-Catalyzed in Situ Synthesis of Temporally and Spatially Distinct CdSe Quantum Dots in Biological Backgrounds Open
The cellular machinery of metal metabolism is capable of making a wide range of inorganic nanoparticles and quantum dots. Individual enzymes from these metabolic pathways are being identified with metal reducing activity, and some have bee…
