Abstract
Disclosed are devices and methods for non-cryogenic vitrification of biological materials that include the steps of providing one or more capillary channels of which a first opening is operably in contact with a moisture containing vitrification mixture made of a biological material and a vitrification agent. The capillary absorbs and transports the moisture to the second opening through capillary action, and the moisture is subsequently evaporated into a surrounding low humidity atmosphere until the vitrification mixture enters into a vitrified state.
Claims9
A non-cryogenic biological material vitrification device comprising:
- a) a receptacle comprising a first membrane and a second membrane, the first membrane, the second membrane, or both comprising a plurality of contiguous capillary channels each having a first opening and a second opening, the first membrane and said second membrane arranged so as to be able to contact a vitrification mixture when placed in the receptacle such that the first membrane contacts a first surface of the vitrification mixture and the second membrane contacts a second surface of the vitrification mixture such that the first opening of said capillary channels is operably in contact with said vitrification mixture;
- and
- b) an enclosure operably in fluidic communication with said second openings of the capillary channels to form an enclosure environment, said enclosure in fluidic communication with an external environment wherein a pressure, temperature, humidity, or combinations thereof within said enclosure environment can operably be controlled.
