Drug Delivery Targeting Security by Optical Capsule Switching Control


Suphanchai Punthawanunt and Preecha P. Yupapin

In this paper, the use of optical capsule for drug delivery with security is proposed. In principle, the optical capsules are generated and formed by soliton pulses within a small scale optical waveguide. The trapped molecules (drug molecules) are brought and stably confined within the device, which can move and deliver securely by the capsule gradient force to the required targets. By using the optical switching control, the trapped drugs within the specific capsules can leave to the access points via the through or drop port, where in this case the switching control is employed by light via the control port (add port). Simulation results obtained have shown that the capsule array can also be constructed and formed the large volume of drug delivery, while the switching control can form the uncapsule drugs into the drug target points. In application, the capsule array can be generated and formed the life molecule trapping, which can be available for life molecule transport within the device, for instance, stem cells, which is useful for stem cells dynamically movement, i.e. transportation to the required targets or organs.
