一种用于三磷酸腺苷(ATP)检测的基于金纳米粒子的检测策略。在没有ATP的情况下,金纳米粒子不会被刚性双链体稳定,因此它们很容易被盐聚集(溶液呈现蓝色);相反,ATP会诱导双链体到适体的结构转换,释放出一种类似无规卷曲的单链DNA。金纳米粒子被释放的单链DNA稳定,对盐诱导的聚集表现出高抗性(溶液保持红色)。
A gold nanoparticle-based detection strategy for ATP assays. In the absence of ATP, gold nanoparticles are not stabilized by the rigid duplex, thus they are readily aggregated by salt (solution displaying blue colors); in contrast induces a duplex-to-aptamer structural switching, liberating a random coil-like ssDNA. Gold nanoparticles are stabilized by the liberated ssDNA, showing high resistance to salt-induced aggregation (solution staying in red).
