Abstract: A novel label-free fluorescence aptasensor was established for chloramphenicol (CAP) detection by DNA four-arm junction-assisted target recycling and SYBR Green I dye-aided fluorescence-signal amplification. The CAP aptamer was hybridized to its complementary strand (primer) to… read more here.

DOI: 10.1109/lawp.2020.2970402
Abstract: Simultaneous transmit and receive (STAR) is attractive because it doubles spectral efficiency and alleviates radio frequency spectrum congestion. As expected, a major challenge in STAR is the high power leakage from the transmitter to the… read more here.
