Recent advances in light-based technologies combined with increasing demand for early diagnostics and improvements in patient care are the major drivers in the expansion of the global biophotonics market with an estimated value reaching $91.3 billion by 2024. To address the growing need for interdisciplinary scientists, clinicians, and engineers,...

A foot pressure assessment system utilizing Fiber Bragg Grating (FBG) sensors is depicted. FBG sensors embedded in a shoe sole measuring pressure distribution in different parts of the foot. Real-time data acquisition enables accurate analysis of foot dynamics, aiding in biomechanical studies and clinical diagnostics. Abstract This research...

Resting-state functional near-infrared spectroscopy can explore the laterality imbalance after stroke from the aspects of cortical activity, functional networks, and hemodynamic lag, all corresponding to the behavioral performance of patients. Abstract Focal damage due to stroke causes widespread abnormal changes in brain function and hemispheric...

In this study, a combination of terahertz time-domain spectroscopy (THz-TDS) and optical coherence tomography is proposed to monitor the changes in refractive index, epidermal thickness, and transmission coefficient of in vivo skin under different states of tension. This work presents a feasible method for measuring in vivo skin by terahertz (THz)...

Diagrammatic representation of the diabetic foot ulcers model in rats treatment by antimicrobial photodynamic therapy. Abstract We investigate the efficacy of photodynamic antimicrobial chemotherapy (PACT) and its combination with an antibiotic in the treatment of diabetic foot ulcers (DFUs) in rats using a novel cationic amino acid porphyrin-based...

The widespread use of Rhodamine B (RhB) in fluorescence imaging underscores the risk of photocytotoxicity, though its exact cause has remained unclear. This study identifies the production of cytotoxic singlet oxygen as the primary cause of photocytotoxicity. Laser power-dependent cellular viability reveals a threshold at about 50 mW cm−2, significantly...
