Photodynamic therapy (PDT) is a great potential approach for the localized tumor removal with fewer metastatic potentials and side effects in treating the disease. In the treatment process, a photosensitizer (PS) that absorbs a light energy to generate reactive oxygen is essential. In general, a vis...

광역학치료란 무엇인가? | 광역학치료는 질병을 치료함에 있어 전이가능성과 부작용이 매우 적고 국부적인 종양의 제거가 가능하다는 장점을 갖는 치료방법이다. 광역학치료에서는 빛 에너지를 흡수하여 세포 독성을 띠는 활성산소를 생성하는 감광제가 필수적이다. | |
감광제의 한계는 무엇인가? | 광역학치료에서는 빛 에너지를 흡수하여 세포 독성을 띠는 활성산소를 생성하는 감광제가 필수적이다. 하지만 일반적인 감광제는 가시광선을 광원으로 사용하므로 이에 따른 부작용 및 치료효과의 한계가 존재한다. 이러한 이유로 가시광선 대신 근적외선을 광원으로 사용할 수 있는 업컨버전 나노입자가 질병진단 및 치료 분야에서 주목을 받고 있다. | |
현재 항암 임상 치료법의 문제점은 무엇인가? | 현재 다양한 항암 임상 치료법이 시도되고 있지만 심한 부작용도 함께 존재한다. 절제 등의 수술법은 암이 빠르게 전이될 위험이 있고, 방사선 치료는 방사능 중독과 이차적인 암의 발달을 야기시킬 수 있다. 화학요법(chemotherapy)은 약물의 낮은 선택성과 독성이 부작용으로 이어질 수 있다. 이러한 문제점이 있기 때문에 효과적이고 부작용이 적은 항암 치료법의 연구개발이 매우 중요하다[1,2]. |
