This paper presents a multifunctional nanotransfer printing (nTP) method based on a simple stick-and-peel procedure that allows fast production of multiple optical nanodevices using Scotch tape. In addition to the capabilities of forming single- and multi-layer nanopatterned films on a tape, the present technique facilitates the transfer of nanostructures onto unconventional substrates (such as cleaved...
A photonic crystal sensor has been demonstrated to enhance photoacoustic signal from light absorbing molecules. The developed system was applied to detect an absorbing dye and gold nanoparticles and exhibited signal enhancement over 40 times.
Gene expression analysis of low abundance genes remains difficult when DNA microarrays are performed on standard glass substrates. However, we have shown that by using photonic crystals (PC) made on quartz substrates, the fluorescence intensity of Cyanine-5 (Cy5) labeled microarray spots is greatly enhanced. In a 1-color microarray experiment studying gene expression of soybean cotyledon tissue, an...
