| titleOfInvention | Up-conversion nanoparticles for detecting horseradish peroxidase, preparation method thereof and detection method of horseradish peroxidase |
| abstract | The invention discloses an up-conversion nano particle for detecting horseradish peroxidase, a preparation method thereof and a detection method of horseradish peroxidase, wherein the preparation method comprises the following steps: 1) 1-octadecene, oleic acid, ytterbium source, gadolinium source, erbium source, sodium source and NH 4 F is subjected to coprecipitation reaction to obtain OA-NaGdF 4 Yb, Er; 2) 1-octadecene, oleic acid, yttrium source, sodium source and NH 4 F and OA-NaGdF 4 In which Yb and Er are coprecipitated to obtain OA-NaGdF 4 :Yb,Er@NaYF 4 UCNPs; 3) mixing Polysuccinimide (PSI), N-Dimethylformamide (DMF) and oleylamine (OAm), adding methanol to the system, and precipitating to obtain PSI OAm Then adding sodium source, chloroform and PSI OAm And OA-NaGdF 4 :Yb,Er@NaYF 4 UCNPs are subjected to ultrasonic treatment to finally obtain-COOH modified NaGdF 4 :Yb,Er@NaYF 4 The upconversion nanoparticles are upconversion nanoparticles for detecting horseradish peroxidase. The up-conversion nanoparticles have the advantages of low detection limit, high sensitivity and good selectivity in detection of horseradish peroxidase. |
