Polydiacetylene (pDA) micelles have been demonstrated to be effective drug carriers for cancer therapy in mouse model. However, little is known about their interaction with the human complement system, which constitutes an important part of the innate immune system and can cause severe hypersensitivity reactions. Herein, we investigate the influence of micelle surface charge on the binding of complement protein C1q, the target recognition unit that activates the classical complement pathway and performs a range of other important physiological functions. Besides the classical pathway, we also investigate the surface charge effect on complement activities through the other activation pathways, namely, the MBL-dependent lectin pathway and the alternative pathway. We synthesized three samples of pDA micelles bearing neutral, anionic, and cationic surface charge motifs, respectively. Surface plasmon resonance showed that none of these micelles interacted with C1q. Results from serum complement activation assays indicated that all micelles were inert to complement, except for the anionic pDA micelles, which activated the alternative pathway.

A novel colloidal catalyst was developed through the encapsulation of cuprous oxide nanoparticles in polydiacetylene micelles. The Cu-based catalyst was applied to the Huisgen cycloaddition reaction in fully aqueous medium. The process neither requires he
