In Figure 1, the first scheme in the panel titled “Controlled polymerization” should be labeled “ring-opening polymerization” instead of “ring-opening metathesis polymerization”. The corrected Figure 1 and caption is provided here. Figure 1. Chemical approaches for the synthesis of defined molecular precursors. A range of synthetic approaches exists for the fabrication of molecular constituents of living biomaterials. For example, controlled polymerizations, including ring-opening polymerization (ROP) as a representative anionic polymerization and atom transfer radical polymerization (ATRP) as a representative radical polymerization, provide access to polymeric species with low polydispersity, defined architecture, and specific chemistry. Postpolymerization functionalization provides an additional strategy to append selected functionality to synthetic polymers via, for example, isocyanate or click chemistry among other strategies. Nucleic acid chemistry and protein engineering enable direct access to biomacromolecules. Lipid and glycochemistry provide additional molecules of life.

对“活生物材料”的更正

在图1中，面板中的第一个方案名为“受控聚合”应标记为“开环聚合”，而不是“开环易位聚合”。此处提供了更正的图1和标题。图1.合成确定的分子前体的化学方法。存在用于制造活生物材料的分子成分的一系列合成方法。例如，受控的聚合，包括作为代表性的阴离子聚合的开环聚合（ROP）和作为代表性的自由基聚合的原子转移自由基聚合（ATRP），提供了具有低多分散性，确定的结构和特定化学性质的聚合物种类的途径。后聚合功能化提供了另一种策略，可通过（例如）将选定的功能附加到合成聚合物上 异氰酸酯或点击化学等策略。核酸化学和蛋白质工程技术可直接访问生物大分子。脂质和糖化学提供了额外的生命分子。本文尚未被其他出版物引用。图1.合成确定的分子前体的化学方法。存在用于制造活生物材料的分子成分的一系列合成方法。例如，受控的聚合，包括作为代表性的阴离子聚合的开环聚合（ROP）和作为代表性的自由基聚合的原子转移自由基聚合（ATRP），提供了具有低多分散性，确定的结构和特定化学性质的聚合物种类的途径。后聚合官能化提供了另外的策略，该策略通过例如异氰酸酯或点击化学等方法将选定的官能团附加到合成聚合物上。核酸化学和蛋白质工程技术可直接访问生物大分子。脂质和糖化学提供了额外的生命分子。
