A multi-piece coverplate assembly provides a multi-piece coverplate and modular device assembly which is removably fastened to the multi-piece coverplate. The process is a free radical copolymerization of a mono-ethylenic monomer, a multi-ethylenic monomer, and a mono-allylic monomer. The proteinaceous channel andor the lipid vesicle are formulated such that the small molecule is released in the vicinity of or near a target cell. The portion of the channel includes a structure that functions as an onoff filter to reflect or transmit an optical signal propagating in the channel in a manner that is responsive to the intensity of the control light beam applied to the portion of the channel. The invention also relates to a micromechanical component which can be produced according to the above method and to its use in sensors such as pressure sensors, microphones, or acceleration sensors. The first and second communication networks include licensed wireless networks, unlicensed wireless networks, or Internet Protocol networks, to name a few.
