Seamlessly Overcoming Biological Barriers with a Small Photosensitizer to Treat Metastatic Tumors with Photodynamic Therapy

Angewandte Chemie, EarlyView.
LUZ 51 is a relatively small and amphiphilic photosensitizer that accumulates in poorly‐vascularized tumors, is rapidly internalized by cancer cells, does not elicit skin photosensitivity and triggers robust immunological responses that reduce spontaneous metastasis.

Photoacoustic effects in nanocomposite structure ‘porous silicon-liquid’ [PDF]

Nanoscale Research Letters, 2012
Abstract Photoacoustic effect in nanocomposite structure ‘porous silicon-liquid’ has been investigated. Main mechanisms involved in the formation of photoacoustic signal in such structures have been experimentally studied. Liquids with different viscosity (ethanol and acetone) filling the nanopores have been used.

STING Agonist‐Modified Tumor Targeting Photosensitizer Remodels Cancer‐Associated Fibroblasts to Potentiate Photoimmunotherapy in Pancreatic Cancer

Advanced Science, EarlyView.
This carrier‐free, esterase‐responsive nanoaggregate integrates a mitochondria‐targeting photosensitizer with a non‐nucleotide STING agonist to achieve localized photoactivation and immune reprogramming. ICyM2 remodels tumor stroma, induces potent immunogenic cell death, and triggers intratumoral STING activation, collectively revitalizing the ...

Real‐Time and High‐Resolution NIR‐II‐L Imaging of Netrin‐1‐Mediated Neurovascular Coupling Driven by Dose‐Dependent Electroacupuncture

Advanced Science, EarlyView.
Disrupted neurovascular coupling contributes to ovarian dysfunction in polycystic ovary syndrome. Using near‑infrared II long‑wavelength imaging, this study visualizes how electroacupuncture dynamically regulates ovarian blood vessels in vivo. Immediate and cumulative stimulation elicit distinct vascular responses via a Netrin‐1 dependent mechanism ...
