药物的结合常在水相环境中与大分子结合，也可在药物进入脂肪组织时发生。

Binding usually occurs when a drug associates with a macromolecule in an aqueous environment but may occur when a drug is partitioned into body fat.

抑制剂一般是小分子，他们不可逆转地结合在受体上阻碍其正常功能，而兴奋剂可以是小或大分子。

Antagonists tend to be small molecules that bind irreversibly to the receptor preventing its normal function, while agonists may be small or large molecules (e.g. peptide or protein hormones).

量子点与生物大分子的连接方式主要有共价耦联结合和静电吸附作用两种。

The two main methods of the connection between QDs and biological molecules are covalent coupling and electrostatic adsorption.
