Abstract: Disclosed herein are compositions and methods for cellular reconstitution of photopolymerized, lyophilized, bioactive chondroitin sulfate glycosaminoglycan (CS-GAG)-based hydrogel matrices.

Abstract: This disclosure provides systems, methods, and apparatus related to infrared spectroscopy. In one aspect, a device includes a first assembly, a porous membrane, and a second assembly. The first assembly defines a fluid distributor. The porous membrane overlies the fluid distributor and forms a surface of the fluid distributor. The second assembly is disposed on the first assembly. The second assembly defines a plurality of capillary arrays surrounding a window in the second assembly that exposes the porous membrane. Capillaries of each of the capillary arrays have openings on edges of the window of the second assembly and are operable to direct moisture across a surface of the porous membrane.

Abstract: The present disclosure provides for microfluidic devices, systems, kits, and methods of using multi-stage microfluidic devices are provided for high throughput sorting, separation/enrichment of target rare cells from a sample, and can additionally provide for characterization/phenotyping of circulating tumor cells (CTCs) and other unlabeled rare cells in a biological sample such as blood, where the rare cells do not need to be labeled.

Abstract: A variety of devices, systems, kits, and methods are provided for separating or enriching circulating tumor cells in a biological sample such as whole blood. In some aspects, the devices are multi-stage devices including at least a filtering stage, and two separation stages for ferrohydrodynamic separation of magnetically labelled white blood cells and for marker-independent and size-independent focusing of magnetically labeled particles so as to separate or enrich unlabeled rare cells in the biological sample. The devices and methods are, in some aspects, capable of high throughput in excess of 6 milliliters per hour while achieving high separation (>97%) of the unlabeled rare cells.

Abstract: Devices for non-invasive, label-free separation of particles in liquid, including circulating tumors cells in blood, are provided. Embodiments of the disclosure provide for devices employing magnetic fluids and magnets for separation of circulating tumor cells from blood. Methods for separation of particles including circulating tumor cells are also provided.
