A method for determining the dissociation constant (K) by plotting resonance frequency shift as a function of time for various target analyte concentrations. From this graph, the fraction of saturation, i.e. equilibrium fraction of bound binding sites out of all available binding sites on the sensor surface may be estimated by taking the ratio of the equilibrium resonance frequency shift at a selected concentration to the equilibrium frequency shift of the sensor. The dissociation constant is the inverse slope of the line produced by graphing the fraction of saturation as a function of concentration. This method is particularly useful for the study of protein-protein and protein-mRNA interactions.

A novel, economical electrical insulation method for the production of ultra-thin insulation layers using a solution coating method. Thin hydrophobic self-assembled bi-functional layers of less than 10 nm thick were deposited by a simple solution method and demonstrated to electrically insulate micro-/nano-devices for in-water detection applications. The insulation layer includes a hydrophobic group which repels water and permits superb insulation properties of the ultra-thin layers. The insulation layer has the additional advantages that it binds to a metal or metal oxide surface and to sensing receptors by covalent bonding using standard silane chemistry.
