The development of a high speed 3D 2-photon microscope for neuroscience

, 2010
The progress of neuroscience is limited by the instrumentation available to it for studying the brain. At present, there is a serious instrumentation gap between functional Magnetic Resonance Imaging (fMRI) of whole brains and the microscopic scale ...

Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

Advanced Science, Volume 13, Issue 33, 15 June 2026.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Translational and rotational motions of albumin sensed by a non-covalent associated porphyrin under physiological and acidic conditions: a fluorescence correlation spectroscopy and time resolved anisotropy study.

, 2008
The interaction between a free-base, anionic water-soluble porphyrin, TSPP, and the drug carrier protein, bovine serum albumin (BSA) has been studied by time-resolved fluorescence anisotropy (TRFA) and fluorescence correlation spectroscopy (FCS) at two ...

Quantum Dots for Biomedical Biosensing, NIR‐II Bioimaging, and Phototherapy: Materials Design, Signal Transduction, and Translational Barriers

Advanced Science, Volume 13, Issue 33, 15 June 2026.
This review outlines bottom‐up and biomimetic fabrication strategies of quantum dots, and highlights their emerging applications in biosensing, multimodal bioimaging, and intelligent cancer theranostics. It further discusses key translational barriers and future perspectives for advancing QD‐based nanomedicine toward clinical implementation.

A near-infrared cell tracker reagent for multiscopic in vivo imaging and quantification of leukocyte immune responses.

PLoS ONE, 2007
The complexity of the tumor microenvironment necessitates that cell behavior is studied in a broad, multi-scale context. Although tomographic and microscopy-based far and near infrared fluorescence (NIRF, >650 nm) imaging methods offer high resolution ...

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Endogenously generated Dutch‐type Aβ non‐fibrillar aggregates dysregulate presynaptic neurotransmission in the absence of detectable inflammation

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract BACKGROUND APPE693Q (“Dutch”) transgenic mice develop aging‐related learning deficits and accumulate endogenously generated non‐fibrillar aggregates (NFAs) of amyloid beta (Aβ) and amyloid precursor protein α‐carboxy terminal fragments. NFA‐Aβ correlates with synaptic loss and memory deficits more closely than does fibrillar Aβ.
