Abstract
Methods, substrates, and devices related to arrays of optical confinements having surfaces with high levels of bias. Substrates having transparent or silica based portions and opaque or reflective portions are treated with 1) a selective passivating agent, that selectively coats the opaque or reflective regions, 2) a functionalizing agent such as a coupling agent, and 3) a selective removal agent, which selectively removes functionalizing agent from the passivated opaque or reflective surfaces.
