摘要： A hybrid microfluidic biochip designed to perform multiplexed detection of singled- celled pathogens using a combination of SPR and epi-fluorescence imaging. The device comprises an array of gold spots, each functionalized with a capture biomolecule targeting a specific pathogen. This biosensor array is enclosed by a polydimethylsiloxane (PDMS) microfluidic flow chamber that delivers a magnetically concentrated sample to be tested. The sample is imaged by surface plasmon resonance on the bottom of the biochip, and epi- fluorescence on the top.

摘要： Systems and methods for rapid and ultrasensitive detection of target hiomolecules in a sample are presented. The detection of biomolecules is achieved through a synergistic use of immunoseparation and diffractomctry, and the formation of antibody-biomolecule-ligand sandwich complexes that form diffraction gratings. Characteristic diffraction patterns are then produced upon illumination of the diffraction gratings with light. The diffraction patterns can he used to detect very low amounts of biomolecules present in the sample.

摘要： Discrete microstructures of predefined size and shape are prepared using sol-gel phase-reversible hydrogel templates. An aqueous solution of hydrogel-forming material is covered onto a microfabricated silicon wafer master template having predefined microfeatures, such as pillars. A hydrogel template is formed, usually by lowering the temperature, and the formed hydrogel template is peeled away from the silicon master template. The wells of predefined size and shape on the hydrogel template are filled with a solution or a paste of a water-insoluble polymer, and the solvent is removed to form solid structures. The formed microstructures are released from the hydrogel template by simply melting the hydrogel template in water. The microstructures are collected by centrifugation. The microstructures fabricated by this method exhibit pre-defined size and shape that exactly correspond to the microwells of the hydrogel template. The method of preparing microstructures based on hydrogel templates is simple and can easily produce large quantities of the microstructures.
