lectroless nickel plating is a relaE. hvely new technological process. The first laboratory experiments were done in 1944 by A. Brenner and G. Riddelll during World War 11. Public announcements were made a few years later. This work bad been done without knowledge of the earlier observations by Roux in 1916* and by Wurtz3 in 1845. The early work was not successful due to poor quality reagents a...

In this paper, we propose a simple (alignment-free) and low-cost microfabrication technique of dual opposite silver electrodes having each separated electrical contact pad inside a microchannel using multiphase laminar flow with density difference, without any photolithographical processes. The electrode patterns were realized by chemical deposition at the interface between a silver electroless...

We present an integrated chemical sensor array fabricated using a CMOS process followed by post-processing. The sensor presented in this paper incorporates 324 individually addressable sensing nodes. Post processing involves an electroless Nickel and Gold plating step to fabricate sensing contacts, and the deposition of a carbon black based polymer sensor material. The operation of the integrat...
