Abstract: Aspects of the disclosure provide techniques for detecting differences and/or changes in biological and non-biological material using infrared imaging. Aspects of the disclosure are useful for monitoring and evaluating synthetic scaffolds and engineered tissue and organs for tissue engineering and transplantation.

Abstract: According to some aspects, supports are provided for producing artificial tissue scaffolds.

Abstract: A fraction collector, sample drier that automatically re-fills sample contains is described. Profiles of RPM and/or back EMF decays as a rotating but unpowered rotor comes to a stop are generated. The profiles may be generated for rotors with full, partially filled and empty sample containers. During a drying operation as the non-volatile samples are collected by evaporating the liquids more sample may be loaded while the rotor is spinning. The operation is to unpower the mechanism and measure the decay profile of PPM and/or EMF over time. A threshold may be set so that the lighter rotor will stop more quickly, and if the threshold is crossed the mechanism will load more sample into the containers.

Abstract: A covered sample plate with wells holding samples to be dried. The cover has through holes that communicate with only a portion of each well. The covered plate is inserted into a cradle of an assembly of cradles that is rotated. The cradle assembly fits into a tub and when rotated the cradles present a sold wall that functions as a centrifugal fan that drives air out through an opening in the tub. The air is dried of solvent and re-circulated back through the through holes in the cover to the sample wells.

Abstract: Articles and methods for growing tissues and organs using bioreactors, including rotating bioreactors, are provided. In some embodiments, a bioreactor is configured to provide a first and second chamber, such as an inner and an outer chamber, respectively. The chambers may be co-axially arranged with respect to each other. A wall of the bioreactor defining the two chambers may be formed at least in part from a scaffold derived from a length of a hollow or tubular tissue or organ. Such a bioreactor can be used to form biocompatible structures for tissue engineering and organ replacement, such as cellular tissues, organ-like structures, and/or complete organs, within the bioreactor.
