Cryopreservation compositions and methods involving nanowarming

A cryopreservation composition generally includes a cryoprotective agent and a laser absorber that includes a metal. Rewarming a cryopreserved specimen that includes the cryopreservation composition includes subjecting the cryopreserved specimen to a laser pulse effective to heat the laser absorber sufficiently to thaw the cryopreserved biospecimen.

CELL STORAGE AND TRANSPORTATION MEDIUM, SYSTEM, AND METHOD OF CELL AGGREGATES

The present disclosure relates to agarose and methylcellulose storage and transport mediums, systems for cell storage and transport, and cell storage and transport methods. The instantly-disclosed agarose and methylcellulose storage and transport medium is ideally suited for 3D spheroid cell culture storage and transport. In particular aspects, the storage and transport mediums, systems, and methods are used in combination with or performed in labware that combine 3D spheroid culture with a gas permeable, micro-patterned design that allows for protection and prolonged maintenance of spheroid cell (e.g. hepatocytes) viability and functionality during storage and transport.

Surface tension mediated lyo-processing technique for preservation of biologics

Methods and devices for lyo-processing biological materials are provided. The methods include submerging the biological molecules or cells in a buffer solution comprising trehalose, withdrawing the biological molecules or cells from the buffer solution in an environment that does not include oxygen to generate lyo-stabilized biological molecules or cells, and storing the lyo-stabilized biological molecules or cells. The devices include a motor that lowers a horizontal member having a clamp for receiving a substrate toward a solvent reservoir and raises the horizontal member having the clamp up and away from the solvent reservoir.
