Silicon to glass

As a future alternative to glassed steel there is ceramics-coated steel which is resistant to abrasion, corrosion and high temperatures. The base metal is coated with silicon nitride formed in situ. Silicon nitride has resistance to both acid and alkali and it is durable at temperatures up to 1 000°C, suggesting a promising future coating in aggressive operating environments.

Two major classes of hydrophobic chemical substances can be applied to glass in ultrathin layers to inhibit surface wetting. Siloxanes or polysiloxanes or silicones are polymers with a backbone of alternating silicon and oxygen atoms. These macromolecules are quite chemically inert, show resistance to water, and exhibit stability at high and low temperatures. The most common siloxane polymer, polydimethylsiloxane, is composed of the monomeric (i.e., repeating) unit illustrated in Fig. 7.5.1. 

An array or a matrix of nucleic acid probes immobilized at discrete locations on a silicon or glass surface provides a convenient means to simultaneously probe a sample for the presence of many different target sequences. Microarray biochip scanning devices, mostly based on fluorescent labels, are now currently available, and could also be used with CL labels to take advantage of the higher sensitivity of this detection principle. 

Immobilization strategies for electrochemical detection may involve physical adsorption, thiol-finking chemistries to gold electrodes, and organosilane finking chemistries to oxidized silicon or glass substrates. Immobilization... 

Abstract We review various methods for the photochemical grafting of organic polymers to various substrates including, organic films, membranes, planar gold, silicon wafers, glass, silica gel, silica nanoparticles, and polydimethylsiloxane micro-channels. An emphasis is placed on photoinitiated synthesis of polymer brushes from planar gold and silicon.
