Islam M, VanderLaan D, Hickman J, Emelianov S, Dickson R
Photoacoustics
. 2023 Aug;
32:100529.
PMID: 37645258
Synchronously Amplified Photoacoustic Image Recovery (SAPhIRe) offers improved background suppression using non-linear properties of modulatable contrast agents. Using SAPhIRe, multiple contrast agents in the same absorption window can be detected...

J Phys Chem B
. 2023 Apr;
127(17):3861-3869.
PMID: 37096986
Time-resolved fluorescence anisotropy (FA) uses the fluorophore depolarization rate to report on rotational diffusion, conformation changes, and intermolecular interactions in solution. Although FA is a rapid, sensitive, and nondestructive tool...

Cytometry A
. 2022 Apr;
101(7):564-576.
PMID: 35426240
Bacterial bloodstream infections are a significant cause of global morbidity and mortality. Constrained by low bacterial burdens of 1-100 colony-forming-units per ml blood (CFU/ml), clinical diagnosis relies on lengthy culture...

. 2021 May;
125(20):5200-5209.
PMID: 33978414
Modulating fluorescent protein emission holds great potential for increasing readout sensitivity for applications in biological imaging and detection. Here, we identify and engineer optically modulated yellow fluorescent proteins (EYFP, originally...

Demissie A, VanderLaan D, Islam M, Emelianov S, Dickson R
Photoacoustics
. 2020 Jul;
20:100198.
PMID: 32685368
In molecular and cellular photoacoustic imaging with exogenous contrast agents, image contrast is plagued by background resulting from endogenous absorbers in tissue. By using optically modulatable nanoparticles, we develop ultra-sensitive...

J Phys Chem A
. 2020 Jan;
124(7):1437-1443.
PMID: 31976677
Fluorescence from the xanthene dyes rose bengal, erythrosine B, eosin Y, and fluorescein is modulated by reversibly optically populating and depopulating their long-lived triplet states through coillumination with a second,...

J Biol Chem
. 2019 Nov;
294(50):19111-19118.
PMID: 31694918
Live cell fluorescence imaging is the method of choice for studying dynamic processes, such as nuclear transport, vesicular trafficking, and virus entry and egress. However, endogenous cellular autofluorescence masks a...

J Phys Chem A
. 2019 Mar;
123(16):3599-3606.
PMID: 30908044
Merocyanine 540 fluorescence can be enhanced by optically depopulating dark photoisomer states to regenerate the fluorescence-generating manifold of the all-trans isomer. Here, we utilize a competing modulation route, long-wavelength coexcitation...

PMID: 30562465
Multinuclear silver clusters encapsulated by DNA exhibit size-tunable emission spectra and rich photophysics, but their atomic organization is poorly understood. Herein, we describe the structure of one such hybrid chromophore,...
