We present an ingenious pressure free NIL (Nanoimprint lithography) method by simply employing a very thin PDMS mold along with a Spin-on-Glass HSQ material. Fabricating nano-patterns (i.e. nano-gratings and 2 D nano-arrays) via NIL is advantageous for LSPR based biosensors for producing large working area with high-throughput. Unlike conventional NIL and other fabrication methods, no complicated...
A sensitive optical method based on quantum dot (QD) technology is demonstrated for the detection of an important cancer marker, total prostate-specific antigen (TPSA) on a disposable carbon substrate surface. Immuno-recognition was carried out on a carbon substrate using a sandwich assay approach, where the primary antibody (Ab)-protein A complex covalently bound to the substrate surface, was allowed...
