Claim:
1. A method for determining a characteristic property of a liquid sample comprising the steps of: a. providing an apparatus adapted for performing light scattering interferometry, the apparatus comprising i. a substrate; ii. a channel formed in the substrate capable of receiving the liquid sample to be analyzed; iii. a light source for generating a light beam; iv. a photodetector for receiving scattered light and generating intensity signals; and v. at least one signal analyzer capable of receiving the intensity signals and determining therefrom one or more characteristic properties of the liquid sample; and b. interrogating the liquid sample using backscattering interferometry, wherein the liquid sample comprises at least two binding partners in a solvent selected from ketone, aldehyde, alkane, chlorocarbon, sulfoxide, and acetonitrile, and wherein a molecular interaction between the binding partners is detected in the liquid sample via the interrogation.
