LED Phototherapy with Gelatin Sponge Promotes Wound Healing in Mice.

Tiny but highly efficient, a light emitting diode (LED) can power a therapy device, such as a phototherapy device, and, at the same time, decrease the device’s size requirements. In this study, a LED phototherapy device was designed to investigate the possible impact on wound healing using a mouse model and a cell line exposed to red and blue light. To enhance wound phototherapy, a gelatin sponge was fabricated. Results showed that the red and blue lights promoted cell growth and wound healing, while the blue light with a gelatin sponge protected the wound from infection in the early stages of wound healing. The LED phototherapy device combined with the gelatin sponge, therefore, has potential significance in clinical application for wound healing.

发光二极管（LED）体积小但效率高，可用于为光疗设备等治疗设备提供动力，同时降低设备的尺寸要求。在这项研究中，设计了一种LED光疗设备，利用小鼠模型以及暴露于红光和蓝光的细胞系来研究其对伤口愈合可能产生的影响。为了加强伤口光疗，制作了一种明胶海绵。结果表明，红光和蓝光促进了细胞生长和伤口愈合，而带有明胶海绵的蓝光在伤口愈合的早期阶段保护伤口免受感染。因此，LED光疗设备与明胶海绵相结合在伤口愈合的临床应用中具有潜在意义。 设计了一种LED光疗设备，利用小鼠模型以及暴露于红光和蓝光的细胞系来检测其对伤口愈合可能产生的影响。为了加强伤口光疗，制作了一种明胶海绵并应用于伤口愈合。结果表明，红光和蓝光促进了细胞生长和伤口愈合，而带有明胶海绵的蓝光在伤口愈合的早期阶段保护伤口免受感染。因此，LED光疗设备与明胶海绵相结合在伤口愈合的临床应用中具有潜在意义。
