Effects of Extreme Mirror Downscaling on Open Micro‐Fabry–Perot Spectral Responses and Resonant Mode Profiles

Advanced Photonics Research, EarlyView.
Extreme miniaturization of Fabry–Perot cavities has severe impacts on their spectral response and spatial distribution of the resonant modes. A fully analytical methodology is proposed accounting for the finite borders of the micromirrors to predict this behavior. Model validation relies on comparing with measurements obtained on silicon micro‐cavities

Copper and Iron‐Based Metal‐Organic Frameworks for Synergistic Cancer Phototherapies: Recent Advances, Challenges, and Future Prospects

Advanced Therapeutics, EarlyView.
The graphical abstract illustrates the combined effect of PTT and PDT using metal‐organic frameworks (MOFs) in a cancer treatment model. Tumor‐bearing mice are irradiated with different laser lights, which activate the MOF nanoparticles within cancer cells. The MOFs produce reactive oxygen species through PDT, while PTT elevates the temperature to kill

Quickly Alternating Green and Red Laser Source for Real-time Multispectral Photoacoustic Microscopy

Photoacoustics, 2020
Multispectral photoacoustic microscopy uses a wavelength-dependent absorption difference as a contrast mechanism to image the target molecule. In this paper, we present a novel multispectral pulsed fiber laser source, which selectively alternates the ...

Systematic Targeting of GD2‐Positive Neuroblastoma Tumors With a Photooncolytic Phage Nanovector Platform

Advanced Science, EarlyView.
A tumor‐penetrating photooncolytic phage is developed for selectively targeting and delivering photosensitizers to GD2‐positive Neuroblastoma cells. Upon light activation, it precisely induces oncolysis of GD2‐positive cells with no effect on GD2‐negative ones.

Photoacoustics meets ultrasound: micro-Doppler photoacoustic effect and detection by ultrasound

, 2014
In recent years, photoacoustics has attracted intensive research for both anatomical and functional biomedical imaging. However, the physical interaction between photoacoustic generated endogenous waves and an exogenous ultrasound wave is a largely unexplored area.
