Abstract
The present invention concerns a high throughput electrorotation chip having an array of electrorotation units and methods of use thereof. To make the high throughput electrorotation chip, a plurality of electrorotation units (EU) are fabricated on a substrate or support and each EU is capable of producing a rotating electric field upon the application of an appropriate electrical signal. Exemplary embodiments include a row-column configuration of EUs having four electrode elements realized through two conductive-layers. The electrode elements may be linear, concave, or convex. Thin plates having one or multiple holes are bound to high-throughput electrorotation chips to form assay chambers having one or multiple wells. Particles can be introduced to the wells and electrorotation measurements can be performed on the particles. The high throughput electrorotation chip and chamber may be used for cell-based screening for leading drug candidate molecules from a compound library, for high-throughput characterizing particle electric properties, and for high-throughput assaying molecular compositions of unknown solutions.
