Journal ArticleDOI
Measuring fast dynamics in solutions and cells with a laser scanning microscope.
Michelle A. Digman,Claire M. Brown,Parijat Sengupta,Paul W. Wiseman,Alan Rick Horwitz,Enrico Gratton +5 more
TL;DR: Novel extensions to ICS are developed that probe spatial correlations in previously inaccessible temporal windows and are used to determine for the first time spatially resolved diffusions of paxillin-EGFP stably expressed in CHOK1 cells.
Journal ArticleDOI
Fluctuation correlation spectroscopy with a laser-scanning microscope: exploiting the hidden time structure.
Michelle A. Digman,Parijat Sengupta,Paul W. Wiseman,Claire M. Brown,Alan Rick Horwitz,Enrico Gratton +5 more
TL;DR: The analysis used to process laser-scanning images of solutions and cells to obtain molecular diffusion constant in the microsecond to second timescale is described.
Journal ArticleDOI
Measuring size distribution in highly heterogeneous systems with fluorescence correlation spectroscopy.
TL;DR: A Maximum Entropy Method based fitting routine (MEMFCS) is introduced that analyzes FCS data in terms of a quasicontinuous distribution of diffusing components, and also guarantees a maximally wide distribution that is consistent with the data.
Journal ArticleDOI
Optogenetic skeletal muscle-powered adaptive biological machines
Ritu Raman,Caroline Cvetkovic,Sebastien G. M. Uzel,Randall Jeffrey Platt,Parijat Sengupta,Roger D. Kamm,Rashid Bashir +6 more
TL;DR: A modular light-controlled skeletal muscle-powered bioactuator that can generate up to 300 µN (0.56 kPa) of active tension force in response to a noninvasive optical stimulus is created, setting the stage for developing multicellular bio-integrated machines and systems for a range of applications.
Journal ArticleDOI
The Amyloid β Peptide (Aβ1-40) Is Thermodynamically Soluble at Physiological Concentrations†
TL;DR: Using fluorescence correlation spectroscopy, Wang et al. as mentioned in this paper showed that Aβ1-40 precipitates in vitro only if the dissolved concentration is > 14 μM, after which the size distribution of Aβ monomer/oligomers in the solution phase becomes stationary in time and independent of the starting Aβ concentration.
