求翻译：因此，本研究首次以壳聚糖、叶酸为基本材料，利用壳聚糖在酸性环境中质子化的氨基与叶酸在碱性环境中去质子化的羧基间的静电相互作用，通过离子交联法合成壳聚糖-叶酸（FA-CTS）微米粒是什么意思？

Therefore, this study is the first to chitosan, folic acid as the basic material, the use of chitosan in the acidic environment of the protonated amino and folic acid in an alkaline environment in the deprotonation of the electrostatic interaction between carboxyl groups by ionic crosslinking Synthe

Therefore, the first study to chitosan, folic acid is the basic materials, using chitosan in an acid environment of the protonated amino and folic acid in an alkaline environment in the carboxyl Proton of the electrostatic interaction between the law, by ion exchange synthetic chitosan - folic acid

Therefore, this research for the first time take the shell polyose, the folic acid as the basic material, the use shell polyose in the acidic environment the protonizing amino and the folic acid in the alkalinity environment between the protonizing electrostatic interaction carboxyl group, through i

Therefore, this study with Chitosan and folic acid as the basic material for the first time, the use of chitosan in protonated amino acid environment and folic acid in alkaline environment in the electrostatic interactions between the protonated carboxyl, synthesized by crosslinked Chitosan by ion-f

So, it is basic materials that this research gathers candies, folic acid with the shell for the first time, the ones that gather the proton in the acid environment of candy with the shell are amino with folic acid the static among the proton carboxyl interacts to the alkaline environment, until ion
