TECHNICAL FIELD The present invention relates to surface-modified nanoparticles for controlling ice formation, comprising nanoparticles; And amino acids or peptides bound to the surfaces of the nanoparticles, it can be applied to biological samples without toxicity, and can be easily synthesized, can increase specific amino acid composition by genetic engineering, and precipitates when used at high concentration It is possible to control freezing and thawing by interacting with ice crystals, to slow down the rate of ice formation during freezing, to minimize damage to cells, to minimize cell death during cold-weathering, Which is capable of minimizing damage during thawing. The present invention relates to surface modified nanoparticles. |
