Far‐field bioluminescent immune cell–mediated photodynamic therapy is limited by photon flux

open access: yesPhotochemistry and Photobiology, EarlyView.
Bioluminescent immune cell‐mediated photodynamic therapy uses tumor‐homing, luciferase‐expressing immune cells as internal light sources to activate photosensitizers in deep‐seated and/or micrometastatic tumors. Using both experiments and computational simulations, we find that this approach delivers insufficient far‐field energy to tumor cells to ...

Understanding extracellular vesicle biology, isolation, and characterization: The theory of EV‐erything

open access: yesPeriodontology 2000, EarlyView.
Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

Experimentally testing the role of blood vessels in the full scattering profile: solid phantom measurements

open access: yesJournal of Biomedical Photonics & Engineering, 2016
Optical methods for biomedical purposes mostly use reflected light, while few of them use the transmitted light. The blood vessels pose a challenge to these methods due to their high absorption and scattering coefficients as well as their change in size ...

The histone deacetylase inhibitor, suberoylanilide hydroxamic acid, restores blood–brain barrier integrity in a human stem cell‐based model of ischaemic stroke

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 19, Page 5791-5812, October 2026.
Ischaemic stroke is characterised by acute cerebrovascular occlusion and blood–brain barrier (BBB) breakdown. Our results indicated that the histone deacetylase inhibitor suberoylanilide hydroxamic acid (SAHA) ameliorated the loss of BBB integrity, changed the morphology of brain endothelial cells, increased the level of basement membrane and ...

Developing our Next Generation BioPhotonics Workstation [PDF]

open access: yes, 2011
Optical trapping and manipulation have established a track record for cell handling in small volumes. However, this cell handling capability is often not simultaneously utilized in experiments using other methods for measuring single cell properties such

Second‐Harmonic Generation Enhancement in Polar Dielectric Films via Nonlocal Longitudinal Modes and Berreman Modes

open access: yesNanophotonics, Volume 15, Issue 18, 25 September 2026.
Nonlocal longitudinal resonances in ultrathin AlN enable thickness‐controlled harmonic matching between a resonance at the fundamental frequency and the Berreman resonance at the second‐harmonic frequency. The resulting simultaneous field enhancement at both frequencies substantially amplifies the predicted second‐harmonic response, revealing a double ...

A solid phantom recipe and exploration for biophotonics applications: A step to produce standardized tissue phantoms

open access: yes, 2020
A well-characterized broadband (600-1100 nm) phantom recipe was presented to manufacture tissue-mimicking optical phantoms over a wider range of optical properties (absorption 0.1-1 cm-1, reduced scattering 5-25 cm-1) relevant to human organs. The recipe
