A novel and effective method for target cells capture and detection is developed in a label-free and real-time mode. The cultured cell line (TZM-bl) expressed as CD4+ was used as the positive CD4+ T lymphocytes for target cells capture and detection experiments. The target cells were captured on various surfaces (such as glass, polydimethylsiloxane, and metal) based on a specific immunity method....
A porous MgO film was grown on sapphire by pulsed-laser deposition. First, small islands of ZnO are grown, and then MgO at a high temperature and high vacuum is deposited. The shortest distance between the two pores is about 5 um. The ZnO grains are grown at the bottom of the pore. The ZnO grains at the rim of the bottom are thinner than that of the centre at the bottom, at which the grains look like...
