Bornite (Cu5FeS4) nanocrystals as an ultrasmall biocompatible NIR-II contrast agent for photoacoustic imaging

Autor: Vinoin Devpaul Vincely, Xingjian Zhong, Kristie Huda, Swathi P. Katakam, Joshua C. Kays, Allison M. Dennis, Carolyn L. Bayer

Publikováno v: Photoacoustics, Vol 40, Iss , Pp 100649- (2024)

In this study, we demonstrate the potential of the bornite crystal structure (Cu5FeS4) of copper iron sulfide as a second near infrared (NIR-II) photoacoustic (PA) contrast agent. Bornite exhibits comparable dose-dependent biocompatibility to copper

Autor: Chloé Grazon, R C. Baer, Uroš Kuzmanović, Thuy Nguyen, Mingfu Chen, Marjon Zamani, Margaret Chern, Patricia Aquino, Xiaoman Zhang, Sébastien Lecommandoux, Andy Fan, Mario Cabodi, Catherine Klapperich, Mark W. Grinstaff, Allison M. Dennis, James E. Galagan

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-10 (2020)

Bacteria represent an unexploited reservoir of biosensing proteins. Here the authors use genomic screens and functional assays to isolate a progesterone sensing allosteric transcription factor and use a FRET-based method to develop an optical progest

Quantifying engineered nanomaterial toxicity: comparison of common cytotoxicity and gene expression measurements

Autor: Donald H. Atha, Amber Nagy, Andrea Steinbrück, Allison M. Dennis, Jennifer A. Hollingsworth, Varsha Dua, Rashi Iyer, Bryant C. Nelson

Publikováno v: Journal of Nanobiotechnology, Vol 15, Iss 1, Pp 1-9 (2017)

Abstract Background When evaluating the toxicity of engineered nanomaterials (ENMS) it is important to use multiple bioassays based on different mechanisms of action. In this regard we evaluated the use of gene expression and common cytotoxicity meas

Bandgap Engineering of Indium Phosphide-Based Core/Shell Heterostructures Through Shell Composition and Thickness

Autor: Reyhaneh Toufanian, Andrei Piryatinski, Andrew H. Mahler, Radhika Iyer, Jennifer A. Hollingsworth, Allison M. Dennis

Publikováno v: Frontiers in Chemistry, Vol 6 (2018)

The large bulk bandgap (1.35 eV) and Bohr radius (~10 nm) of InP semiconductor nanocrystals provides bandgap tunability over a wide spectral range, providing superior color tuning compared to that of CdSe quantum dots. In this paper, the dependence o

Förster Resonance Energy Transfer between Quantum Dot Donors and Quantum Dot Acceptors

Autor: Kenny F. Chou, Allison M. Dennis

Publikováno v: Sensors, Vol 15, Iss 6, Pp 13288-13325 (2015)

Förster (or fluorescence) resonance energy transfer amongst semiconductor quantum dots (QDs) is reviewed, with particular interest in biosensing applications. The unique optical properties of QDs provide certain advantages and also specific challeng

In Vivo Biosensing Using Resonance Energy Transfer

Autor: Shashi Bhuckory, Joshua C. Kays, Allison M. Dennis

Publikováno v: Biosensors, Vol 9, Iss 2, p 76 (2019)

Solution-phase and intracellular biosensing has substantially enhanced our understanding of molecular processes foundational to biology and pathology. Optical methods are favored because of the low cost of probes and instrumentation. While chromatogr
