Micro needle transmits medications and light
Positioning this technology in the
Functionality Grid
Reformatted from: Van Wyk, Rias J: Technology - A Unifying Code, 2004, SMG, Cape Town, p.34. Based on: Ropohl, Gunter: Eine Systemtheorie der Technik, 1979, Carl Hanser Verlag, Munich and Vienna, p.178.
This Newsbrief deals with a unique medical delivery device - an ultra-fine needle that delivers both medication and light. In terms of the Atlas of Technology it is concerned with the transport of matter (M) and energy (E).
Medical technology is continuously striving to create more accurate and versatile medication delivery systems.

Towards the end of 2012 a unique needle was reported. [Lobel, M. "A revolutionary cancer treatment device inspired by the mosquito" Spectrum, September.] C. Rylander, a mechanical engineer at Virginia Tech has designed a needle using extremely fine optic fiber, about 40 microns thick. This allows it to be used for injections with minimal harm to the tissue being penetrated.

A further unique feature of the needle is that it combines two cancer fighting therapies in one device:
  • The delivery of medication
  • The delivery of sharply focused laser light
Referred to as a fiber-optic microneedle device (FMD), the needle can be used to deliver cancer medication accurately to a cancer tumor. Such medications can be conventional chemotherapy-drugs or more cutting edge medications such as nano particles. In addition the FMD can also deliver light from powerful lasers. While conventional lasers deliver finely focused light, beams scatter when they come into contact with tissue. By using the FMD, light can be more precisely delivered, and combined with light absorbing nano particles.
On the NASA nine point scale of technology readiness levels (TRLs), this technology is at level 3. Technology explorers should anticipate further approaches using the dual use FMD.
