Abstract

Cryonics is the preservation of the human body in low temperatures with the hope of reviving it in the future. This comprehensive article navigates through the three stages of cryonics: Preparation, Stasis, and Revival. In the Preparation phase, from the deployment of standby teams upon legal death announcement to cryoprotectant perfusion, which replaces bodily fluids with solutions to minimize freezing damage. Vitrification is an innovative technique, countering ice crystallization and reducing the dependence on precise optimal cooling rates. The cryoprotective agents, permeable and nonpermeable, are required to assist vitrification. As a result, it is important to take into account the toxicity of cryoprotective agents. Stasis, the immersion in liquid nitrogen, secures long-term preservation. Cryostats and Dewars serve as the guardians of cryonics temperatures, maintaining a stable environment. Revival, the final stage, is determined by precise rewarming and cell repair. Nanotechnology might be applied to the warming and repairing procedures. Understanding cell volume dynamics and harnessing nanotechnology’s potential increases the possibility of successful revival. This article aims to provide an examination of Cryonics.
