WebApr 22, 2016 · The instability of PEGylated polylactide micelles is a challenge for drug delivery. Stereocomplex interaction between racemic polylactide chains with different configurations provides an effective strategy to enhance the stability of micelles as the nanocarriers of drugs. In this work, a stereocomplex micelle (SCM) self-assembled from … WebPlastics are composed of polymers--large molecules consisting of repeating units called monomers. In the case of plastic bags, the repeating units are ethylene, or ethene. When …
