Extracellular electron transfer via microbial nanowires.
Gemma Reguera,Kevin D. McCarthy,Teena Mehta,Julie S. Nicoll,Mark T. Tuominen,Derek R. Lovley +5 more
TL;DR: Results indicate that the pili of G. sulfurreducens might serve as biological nanowires, transferring electrons from the cell surface to the surface of Fe(iii) oxides, indicating possibilities for other unique cell-surface and cell–cell interactions, and for bioengineering of novel conductive materials.

Glucose oxidase anode for biofuel cell based on direct electron transfer
TL;DR: In this paper, a new design concept of a glucose oxidase (GO x ) electrode as an anode for the biofuel cell based on direct electron transfer (DET) between the active site of an enzyme and the multi-walled carbon nanotube (MWNT)-modified electrode surface was presented.
Journal ArticleDOI
Entrapment of enzymes and carbon nanotubes in biologically synthesized silica: glucose oxidase-catalyzed direct electron transfer.
Dmitri Ivnitski,Kateryna Artyushkova,Rosalba A. Rincón,Plamen Atanassov,Heather R. Luckarift,Glenn R. Johnson +5 more
TL;DR: A new approach for building bioinorganic interfaces is demonstrated by integrating biologically derived silica with single-walled carbon nanotubes to create a conductive matrix for immobilization of enzymes and can be successfully integrated into functional bioelectrodes for biosensor and biofuel cell applications.
Journal Article
In vivo imaging with quantum dots encapsulated in phospholipid micelles
TL;DR: In this paper, the authors encapsulated individual nanocrystals in phospholipid block-copolymer micelles and demonstrated both in vitro and in vivo imaging, and the nanocrystal-micelles acted as in vitro fluorescent probes to hybridize to specific complementary sequences.
Journal ArticleDOI
Direct Bioelectrocatalysis of PQQ‐Dependent Glucose Dehydrogenase
TL;DR: A fusion of PQQ-dependent GDH with SWNTs has a great potential for the development of low-cost and reagentless glucose sensors and biofuel cells.

Semiconductor Nanocrystals as Fluorescent Biological Labels
TL;DR: Semiconductor nanocrystals prepared for use as fluorescent probes in biological staining and diagnostics have a narrow, tunable, symmetric emission spectrum and are photochemically stable.
Journal ArticleDOI
Quantum Dot Bioconjugates for Ultrasensitive Nonisotopic Detection
Warren C. W. Chan,Shuming Nie +1 more
TL;DR: Highly luminescent semiconductor quantum dots (zinc sulfide-capped cadmium selenide) have been covalently coupled to biomolecules for use in ultrasensitive biological detection and these nanometer-sized conjugates are water-soluble and biocompatible.
Journal ArticleDOI
Stochastic Gene Expression in a Single Cell
TL;DR: This work constructed strains of Escherichia coli that enable detection of noise and discrimination between the two mechanisms by which it is generated and reveals how low intracellular copy numbers of molecules can fundamentally limit the precision of gene regulation.
Journal ArticleDOI
A synthetic oscillatory network of transcriptional regulators
TL;DR: This work used three transcriptional repressor systems that are not part of any natural biological clock to build an oscillating network, termed the repressilator, in Escherichia coli, which periodically induces the synthesis of green fluorescent protein as a readout of its state in individual cells.
Journal ArticleDOI
Construction of a genetic toggle switch in Escherichia coli
TL;DR: The construction of a genetic toggle switch is presented—a synthetic, bistable gene-regulatory network—in Escherichia coli and a simple theory is provided that predicts the conditions necessary for bistability.
