<p>Methods and apparatus for screening diverse arrays of materialsa nd for imaging a library of materials are provided using ultrasonic imaging techniques. Systems include tranducer lens (109) or mechanical resonator for exiting an element of library deposited onto a substrate (103) such that acoustic waves are propagated through, and from, the library element (101). The acoustic waves propagated from the element are detected and processed to yield a visual image of the library element; such acoustic wave data is processed to obtain information about various properties of the library elements (e.g. elasticity, molecular weight, viscosity, specific weight, dielectric properties, conductivity, etc.) of individual liquid elements. Acoustic waves are generated in an imaging tank filled with coupling liquid (107), with the library of materials then placed in the tank while the surface of the coupling liquid is scanned with a laser beam. The physical structure of the liquid surface distubed by these acoustic waves is recorded.</p> |
