Light-induced drug delivery with indocyanine green liposomes
Introduction to light-controlled drug delivery systems Study description It is important that light-triggered liposomes efficiently release their contents, while the liposome stability should be maintained in the absence of laser light. The aim of this study is to determine how liposomal stability and drug release are affected by liposomal formulation. Indocyanine green was used as the light-sensitizing compound

Modulight Spotlights: LASER-SHARP RESEARCH – July 2022
Dr. Makoto Mitsunaga et al. Jikei University School of Medicine published in Communications Biology journal about developing a next-generation light-based approach to tackle pathogens, called photoimmuno-antimicrobial strategy (PIAS). This technology was shown to eliminate a broad spectrum of different classes of pathogens, such as viruses, fungi, and bacteria.

Light delivery optimization for H&N cancer treatment
Results Illumination with one fiber Some level of tissue heating was observed at all used light intensities. At lower intensities (60-100 mW/cm), less than 5% of the tumor was subjected to >60 ⁰C temperature, a point where irreversible thermal damage will immediately occur (photothermal ablation). At intensities of 150-200 mW/cm, 15-20% of the tumor was
