Journal ArticleDOI
Quantum dot display enhances activity of a phosphotriesterase trimer
Joyce C. Breger,Joyce C. Breger,Scott A. Walper,Eunkeu Oh,Kimihiro Susumu,Michael H. Stewart,Jeffrey R. Deschamps,Igor L. Medintz +7 more
TL;DR: Phosphotriesterase was engineered into a spontaneously forming trimer by appending it to a synthetic collagen-like triple-helix motif that increased the enzyme's catalytic rate and efficiency.
Journal ArticleDOI
The Role of Negative Charge in the Delivery of Quantum Dots to Neurons.
Ryan Walters,Igor L. Medintz,James B. Delehanty,Michael H. Stewart,Kimihiro Susumu,Alan L. Huston,Philip E. Dawson,Glyn Dawson +7 more
TL;DR: It is confirmed both that preferential uptake in neurons, and the lack of uptake in glia, is strongly associated with having a region of greater negative charge on the QD coating, as well as the future potential of using QDs as vehicles for trafficking proteins into cells continues to show promise.
Journal ArticleDOI
Three-Dimensional Solution-Phase Förster Resonance Energy Transfer Analysis of Nanomolar Quantum Dot Bioconjugates with Subnanometer Resolution
K. David Wegner,Frank Morgner,Eunkeu Oh,Ramasis Goswami,Kimihiro Susumu,Michael H. Stewart,Igor L. Medintz,Niko Hildebrandt +7 more
TL;DR: A detailed FRET study on a large set of QD–biomolecule conjugates is presented, which allows for a homogeneous solution-phase size, shape, and bioconjugation analysis.
Journal ArticleDOI
Site-specific cellular delivery of quantum dots with chemoselectively-assembled modular peptides
James B. Delehanty,Juan B. Blanco-Canosa,Christopher E. Bradburne,Kimihiro Susumu,Michael H. Stewart,Duane E. Prasuhn,Philip E. Dawson,Igor L. Medintz +7 more
TL;DR: Modular peptides displaying both quantum dot bioconjugation motifs and specific subcellular targeting domains were constructed using a chemoselective aniline-catalyzed hydrazone coupling chemistry to facilitate their specific delivery to either the plasma membrane, endosomes, the cytosol or the mitochondria of target cells.
Journal ArticleDOI
Synthesis, Structure, and Reactivity of Four-, Five-, and Six-Coordinate Ruthenium Carbyne Complexes
Stephen R. Caskey,Michael H. Stewart,Yi Joon Ahn,Marc J. A. Johnson,Jesse L. C. Rowsell,Jeff W. Kampf +5 more
TL;DR: In this paper, the Grubbs catalysts Ru(CHR)(PCy3)2Cl2 were used to synthesize square-planar carbyne complexes of the form Ru(C-p-C6H4Me)2X (X = F, Cl, Br, I, O3SCF3).
