Manufacturing Nanoimprint Lithography System to Produce Efficient Microneedles Patch for Transdermal Drug Delivery
Rizgar Jiawook
Journal of Applied Biotechnology & Bioengineering
June 9, 2017
This paper describes a sophisticated device for delivering drugs continuously via the skin to the systemic circulation in the human body. The Nanoimprint Lithography (NIL) system was manufactured for the first time by Obducat AB to make this possible. The system comprises of the NIL process to imprint a pattern on a foil with nano structure that mimics human cell structure, resulting in a very efficient Microneedles Patch for Transdermal Drug Delivery.

When Nanophotonics Meet Thin Crystalline-Silicon Photovoltaics
Rizgar Jiawook and 10 colleagues
EUPVSEC 2015, Conference Proceedings (3DO.13.4), Hamburg, Germany
September 14, 2015
This paper discusses how the "Lambertian limit" of light trapping may be overcome by texturing crystalline silicon solar cell surfaces at the wavelength scale. It presents results from the PhotoNVoltaics project, suggesting that the ideal thin c-Si solar cell is a heterojunction back-contact cell with inverted nano-pyramids at its front side.
