Study on nanomaterials has attracted great interests in recent years. In this article, zirconia nanocrystallites of different structures have been successfully synthesized via hydrothermal methods with cationic surfactant （CTAB） and anionic surfactant （SDS）, respectively. Differential Scanning Calorimeter （DSC-TG）, X-ray Diffractometer （XRD）, Transmission Electron Microscope （TEM）, Ultraviolet-Visible （UV-vis） and N2 adsorption-desorption analyses are used for their structure characteristics. The results show that the cationic surfactant has a distinctive direction effect on the formation of zirconia nanocrystallites, while the anionic surfactant has a self-assembly synergistic effect on them. The sample synthesized with the cationic surfactant presents good dispersion with the main phase of tetragonal zirconia, and the average nanocrystal size is around 15 nm after calcination at 500 ℃. While the sample synthesized with the anionic surfactant exhibits a worm-like mesoporous structure with pure tetragonal phase after calcination at 500 ℃ and with good thermal stability.

结核病(tuberculosis,TB)流行病快速筛查常采用结核菌素纯蛋白衍生物(pure protein derivative,PPD)皮试,但特异性低,不良反应大。ESAT-6和CFP-10是结核分枝杆菌的分泌蛋白,但卡介苗(Bacillus Calmette-Guerin,BCG)中缺失了相关基因。本研究表达纯化了结核分枝杆菌的分泌蛋白ESAT6和CFP10的融合蛋白(ESAT6 and CFP10 fusion protein,EC),并制备成其壳聚糖纳米粒(ESAT6 and CFP10 fusion protein nanoparticals,EC-NPs),进一步制备成透明质酸可溶性微针贴片(microneedle patch,MNP)。MNP-EC-NPs载药量达到每针0.03μg,每片可达到1.92μg,常温下保存期可达6个月,可有效透过表皮。志愿者皮试结果显示MNP-EC-NPs可有效区分BCG接种者,在结核病患者皮肤有效显示阳性反应,无显著不良反应,实验经武汉市肺科医院伦理委员会批准[武肺伦理2022(2)]。本研究建立了一种结核病皮试方法,采用ESAT6-CFP10融合蛋白替代PPD,并采用可溶性微针剂型,提高了结核病皮试诊断的特异性,为结核流行病筛查提供了新的技术方案。
