We designed a tandem stimuli-responsive assembly based on a guanidinium-modified calix[5]arene (GC5A-6C) and eosin Y modified hyaluronic acid (EY-HA), which showed hyaluronidase-triggered disassembly and ATP-activated release of EY. Both hyaluronidase and ATP are tumor biomarkers, and therefore, the present system shows potential in precision delivery with respect to tumor phototheranostics.
我们设计了一种基于胍基修饰杯[5]芳烃（GC5A-6C）和吖啶黄修饰透明质酸（EY-HA）的串联刺激响应组装体，该组装体在透明质酸酶的触发下发生解组装，并在 ATP 的激活下释放 EY。透明质酸酶和 ATP 均为肿瘤生物标志物，因此，该体系在肿瘤光疗方面具有精准递药的潜力。
