摘要
以去铁铁蛋白作为生物模板合成了硒化锌量子点,采用Langmuir-Blodgett技术在硅基质表面制备1:4的EA/SMA的LB薄膜并将硒化锌核铁蛋白吸附组装到EA/SMA薄膜上形成二维阵列。用紫外-可见吸收光谱(UV-Vis)、荧光光谱(PL)、傅里叶转换红外光谱(FTIR)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)进行表征,结果表明成功制备得到了硒化锌量子点核铁蛋白单分子层二维阵列。这种排列在固体表面的有序微观尺寸的纳米结构由于其独特的光学和生物学特性在生物传感、药物和诊断等领域具有潜在的应用前景。
Zinc selenide （ZnSe） nanocrystals were synthesized by bio - template of apoferritin from horse spleen （ HsAFr）, and the two - dimensional ZnSe - ferritin nanodots were prepared on modified silicon surface by Langmuir - Blodgett method using the adsorption properties of a 1/4 mixed monolayer of eico- sylamine （EA） and methyl stearate （SME）. The obtained nanodots were characterized by UV -Vis Ab- sorption, Photoluminescenee Spectroscopy （PL）, Fourier Transform Infrared Spectroscopy （NFIR） and Scanning Electron Microscope （ SEM）, Transmission Electron Microscope （TEM） measurements. From the results, it was concluded that the ZnSe nanoerystals were successfully synthesized in the core of fer- ritin and the monolayer of the ZnSe - ferritin could be obtained on the surface of silicon wafer. According- ly, the ZnSe -ferritin arrays can be employed as a useful detection material for PL technique in biosen- sor, drug and diagnostic development.
