As medical technology continues to advance, photodynamic therapy—a biological process based on photochemical reactions—has emerged as a precise treatment modality for conditions like acne and tumors, garnering favor within the medical community. This therapy leverages the interaction between photosensitizers and oxygen, activating photosensitizers through laser irradiation, to selectively target and destroy diseased tissues, facilitating minimally invasive or non-invasive tumor treatments. In developed nations, photodynamic therapy has become a standard approach to tumor treatment, with its clinical application in China also gaining increasing traction.

 

Remaining attuned to industry trends, BWT has unveiled the MF series bar coupling components, capitalizing on the profound tissue penetration of red light. These components are tailored for treating deep-seated lesions or sizable tumors, injecting fresh vigor into the global adoption of photodynamic therapy.
