Protecting complex nanostructures from degradation in physiological fluids while preserving their function remains a major limitation toward their implementation in biosensing and drug delivery. Using peptoid oligomers, Gang and coworkers protect DNA origami structures from Mg²⁺ depletion and enzymatic breakdown.

分子保护器：纳米结构的超级英雄

保护复杂的纳米结构免于在生理液体中降解，同时保持其功能仍然是其在生物传感和药物输送中实施的主要限制。使用拟肽寡聚物，Gang 和同事保护 DNA 折纸结构免于 Mg ²⁺耗尽和酶促分解。
