ZnO is an important functional material owing to its fascinating optical, piezoelectric, semiconductivity and pyroelectric properties and has been largely applied in optoelectronic devices, sensors and displays. For the application in phosphors, ZnO has been made into mostly micro-powders in a monotonic spherical shape by solution routes. Nano-phosphors with well-defined shapes of high symmetry …

The current study presents a new miniature microfluidic flow cytometer integrated with several functional micro-devices capable of viral sample purification and detection by utilizing a magnetic bead-based immunoassay. The magnetic beads were conjugated with specific antibodies, which can recognize and capture target viruses. Another dye-labelled anti-virus antibody was then used to mark the …

The recent advances of micro and nano fabrication technologies have allowed the realization of highly complex patterns on planar light-wave circuits (PLCs). Coupling the new fabrication capability with the rapid advance of computing power, it is now possible to calculate and fabricate a refractive index distribution as a hologram on a waveguide. We have demonstrated a new class of devices using …

Oct-3/4 (also known as Oct-4, Oct-3 and POU5f1), a member of the POU family, is an octamer-binding transcription factor that is a key regulator in undifferentiated, pluripotent cells including human embryonic stem cells and germ cells. Oct-3/4 has been demonstrated to be a sensitive and specific immunohistochemical marker of gonadal germ cell tumors, specifically seminoma and embryonal carcinoma. …
