Abstract: Laser photodynamic therapy equipment is difficult to remove the large area of tumor cells in clinic.A new method for rapidly removing tumor in larger area is developed.The control system that employs temperature sensor,integrated circuits,air cooling technique and nanoparticle light-scattering effect,turns the light of series connection and parallel LED assays into 3D cold light source uniformly.The liquid crystal display,irradiation temperature,power,time,and brightness are adjustable by digital combined logic circuit.The emission wavelengths of the therapeutic device range from 400 nm to 2 000 nm with different lamp bead.Initial experiments demonstrated that the device could rapidly kill and eliminate tumor cells in large area.The therapeutic apparatus can synergistically treat cutaneous tumor or superficial cancer with photosensitizer and targeted absorbing nanomaterial at visible light to near infrared wave band.
