The capsular antigen detection (CAD) kit is widely used in clinics to detect Streptococcus pneumoniae infection from urine, because it is rapid, convenient, and effective. However, there are several disadvantages, including false-positive results in children colonized with S. pneumoniae and prolonged positive readings even after the bacteria have been(More)
We demonstrate a high dynamic range, three-dimensional (3-D) terahertz (THz) wave computed tomography system in which frequency tunable, Fourier transform-limited, high-power THz waves are emitted by an injection-seeded parametric source and ultrasensitive detection of THz waves is accomplished by heterodyne detection. This system covers the frequency range(More)
A concise liquid-phase combinatorial synthesis of all stereoisomers of Tenuecyclamide A was achieved using a mixture of D-/L-alanine with each stereoisomer encoded by a different f-Fmoc tag. The synthetic strategy using f-Fmoc reagents as the protecting group for amino acids has been demonstrated to be a useful method for diverse polypeptide analogue(More)
