Abstract
Disclosed herein are microfluidic devices and methods to deliver concentration gradients to biological material such as oocytes and embryos for the purpose of cryopreparation, cryopreservation, or thawing. Cryopreservation methods, such as vitrification, involve the use of cryoprotectants to reduce formation of damaging ice crystals in cells during freezing. Microfluidic devices and methods described herein improve cell viability and efficiency during handling and cryopreservation of biological materials.
