稳健的荧光素掺杂的二氧化硅纳米粒子的合成通过传统的Stöber方法和以下稠密液体处理。所制备的纳米粒子在较宽的pH值范围内均呈现稳定的荧光。BET测量显示密液过程有效地封闭二氧化硅表面的孔，从而有效地防止质子渗透到颗粒中。
Robust fluorescein-doped silica nanoparticles were synthesized by the conventional Stöber method and following dense-liquid treatment. The as-prepared nanoparticles present stable fluorescence in a wide range of pH value. BET measurements show the dense-liquid process is effective to close the pores of the silica surface and thus effective to prevent the penetration of protons into the particles.
