Abstract: A computer-implemented method of an exhibitor interacting with a visitor and acquiring, managing, and qualifying leads, comprises: receiving identification information from the visitor at an input station; matching the identification information to a visitor account; and transmitting a notification of attendance by the visitor at the input station to a contact other than the visitor, defined for the visitor account by the exhibitor. The method may further comprise: collecting behavior information from the visitor defining one or more of type, quality and quantity of interactions between the visitor and the exhibitor, during the interactions; and updating records in a leads database linking the visitor account to the behavior information, while collecting the behavior information.

Abstract: The present invention provides a microfluidic device that can be used for fiber optic interrogation of multiple samples. The device comprises a substrate integrally comprising a plurality of optic fibers. A layer formed on a surface of the substrate defines at least one topological feature that communicates with at least one optic fiber for interrogation of a sample. The device preferably comprises a plurality of topological features that may include a patterned array of wells, channels or any combinations thereof. The plurality of optic fibers of a device of the invention are capable of interrogating thousands of samples simultaneously. These samples may include, without limitation, molecular, cellular, proteomic, genomic or gaseous materials or assays. The present invention also discloses a method for fabricating a microfluidic device. The invention also comprises a method for interrogating multiple samples in parallel via the microfluidic devices provided herein.
