Article Abstract
Cyborg insects offer a biologically powered solution for locomotion control, but conventional methods typically rely on invasive electrical stimulation. Here, we introduce a noninvasive, phototaxis-based strategy to steer walking beetles using light-emitting diode (LED) stimuli. Electroretinogram recordings revealed spectral sensitivity to blue, green, and yellow light, with reduced response to red. Behavioral assays demonstrated robust positive phototaxis to blue light and negative phototaxis to yellow. Using these findings, we built a wireless microcontroller-based backpack emitting directional blue light to induce steering. The beetles reliably turned toward the activated light, achieving angular deflections over 60° within seconds. This approach enables repeatable, trauma-free insect control and establishes a new paradigm for biohybrid locomotion systems.

To evaluated the efficacy of photodynamic therapy (PDT) in improving laryngeal mucosal wound scar healing in vivo and investigated its underlying mechanisms. Laryngeal mucosal wounds were induced in Sprague-Dawley rats. Two weeks post-injury, PDT was administered via intraperitoneal injection of 100 mg/kg 5-aminolevulinic acid (5-ALA) and 635-nm red laser irradiation at varying energy doses (15, 30, and 45 J/cm²).

Photoremovable protecting groups (PRPGs) enable precise spatiotemporal control over molecular release and functional activation. Recent advances have introduced wavelength-selective systems for sequential deprotection, broadening applications in drug delivery, material synthesis, and photopolymerization. In parallel, PRPGs play a crucial role in photobase generators (PBGs) and photoacid generators (PAGs), enabling oxygen-tolerant, spatially controlled polymerization and depolymerization through light-induced base and acid release.

Antibacterial photodynamic therapy offers a promising approach for combating both susceptible and multidrug-resistant pathogens. However, conventional photosensitizers have limitations in terms of poor binding specificity and weak penetration for pathogens. In this study, we developed synergistic photobactericidal polymers that integrate hydrophilic toluidine blue O (TBO) with the lipophilic penetration enhancer citronellol (CT).

Microalgae and their rich nutrient content are increasingly recognized as a sustainable food source. Microalgal macular pigment (MP), composed of zeaxanthin and lutein, is densely concentrated in the retinal macula of eyes and is frequently utilized in eye health maintenance. However, as a sustainable food ingredient, the food safety and functionality of MP need further investigated.

Artificial light at night (ALAN) can disrupt numerous biological processes, and is increasingly studied in animal models. Here, we evaluated the impact of red and blue ALAN on Drosophila melanogaster, focusing on fertility, development, circadian rhythms, and gene expression. All results were compared to those of a control group maintained under a 12 h white light/12 h dark cycle.
