Programmable three‐state nanoreactor for spatiotemporally controlled tumor therapy

BMEMat, EarlyView.
The OMVs are shielded with a biocompatible Da–Ca shell, which prolongs its circulation period and promotes intratumoral accumulation. Importantly, the biocompatible Da–Ca shell can be controllably disintegrated in tumor microenvironment by using laser irradiation, generating in situ hyperthermia and releasing Ca2+.

Spatiospectral Photoacoustic Microscopy With Gain‐Switched Ti:Sapphire Laser for High‐Accuracy Molecular Dynamics Imaging

Laser &Photonics Reviews, EarlyView.
Spatiospectral photoacoustic microscopy is enabled by stable, wavelength‐tunable dual‐pulse excitation from a gain‐switched Ti:sapphire laser. Intrinsically synchronized 532‐nm and NIR‐I pulses provide single‐scan, co‐registered mapping of oxygen saturation and indocyanine green dynamics in vivo.

Bio‐Derived Nanophotonic Hybrids Enabling Reconfigurable Upconversion for Multilevel Optical Encryption

Laser &Photonics Reviews, EarlyView.
A dual‐gated nanophotonic platform integrates lanthanide‐doped upconversion nanoparticles with a stimuli‐responsive silk–zirconia photonic crystal to enable multilevel optical encryption. Resonant photonic coupling allows hydration‐dependent modulation of visible emission under near‐infrared excitation, achieving reversible switching between decoy and ...

Heterogeneous camera array for multispectral light field imaging

Optics Express, 2017
Multispectral light field acquisition is challenging due to the increased dimensionality of the problem. In this paper, inspired by anaglyph theory (i.e. the ability of human eyes to synthesize colored stereo perception from color-complementary (such as red and cyan) views), we propose to capture the multispectral light field using multiple cameras ...

Multispectral Mid‐Infrared Imaging With Incoherent Light via Adiabatic Upconversion

Laser &Photonics Reviews, EarlyView.
We demonstrate room‐temperature broadband MIR imaging based on adiabatic frequency upconversion, driven by a Q‐switched pump laser and incoherent illumination. The small‐foot‐print system upconverts the spectral range to the visible domain, without scanning, thermal control and with spatial resolution below 20μm$20\mathrm{\mu}\mathrm{m}$.
