Application

<ul>
<li><strong>Application in hydrophilic fluorescent nanozymes: </strong>4-Chlorobutyric acid is used in the synthesis of Mn2+:CsPbCl3@SiO2 yolk shell nanoparticles (YSNPs) through the SN2 reaction with oleylamine (OAm). This reaction yields a zwitterionic ligand that facilitates the dispersion of YSNPs in water (Wang et al., 2024).</li>
