Abstract
Progress of nanotechnology for phototherapy: Fundamentals and applications
Highlights
Nanotechnology has been developed for both industrial and medical applications
For the case of one light for both photothermal therapy (PTT) and photodynamic therapy (PDT) the simultaneously interacting with the nanogold and the photosensitizer is much more complex that of the case of two different lights which can be treated independently
We have previously studied and analyzed in vitro photothermal destruction of cancer cells using gold nanorods and pulsed-train near-infrared [8,9]
Summary
Nanotechnology (nano-materials and nano-process) has been developed for both industrial and medical applications. C(z,t) depends on both t and z, and can be depleted in PDT, especially in type-I process If one includes this effect, coupled equations for dC/dt, and dI/dz are required and needed to be solved simultaneously with Eq (1). All the previous studies [21,22,23,24,25] assumed a type-II process (with p=0) and the PS is almost not consumed for the treatment period of 10 to 30 minutes, and the light intensity is given by a timeindependent Lambert-Beer law, that is C(z,t) in Eq (2.e) is assumed to be a constant C0.
