    • The present invention discloses a urinal with a conductivity sensor, which includes the conductivity sensor arranged at the location where a reservoir of the urinal is curved and adapted to detect urine, a control unit (MCU), a power battery, and an electromagnetic valve adapted to control a discharge of water, wherein the conductivity sensor is adapted to detect a conductivity to determine whether urine is present. After the conductivity sensor detects presence of urine, the control unit opens the electromagnetic valve. The conductivity sensor includes electrodes dipped inside the location where the reservoir is curved to contact urine. The conductivity sensor further includes an anti-polarization-of-electrode circuit based upon the principle of an alternating power supply. Thus, the sensor can achieve more reliable sensing and a longer lifetime.
    • 本发明公开了一种具有电导率传感器的小便池,其包括布置在小便池的容器弯曲并适于检测尿液的位置处的电导率传感器,控制单元(MCU),动力电池和电磁阀 以控制水的排放,其中所述电导率传感器适于检测导电性以确定是否存在尿。 在电导率传感器检测到尿液的存在之后,控制单元打开电磁阀。 电导率传感器包括浸在容器弯曲接触尿液的位置内的电极。 电导率传感器还包括基于交流电源的原理的反极化电极电路。 因此,传感器可以实现更可靠的感测和更长的寿命。

    • The present invention provides multiple-luminophore silica nanoparticles for multiplexed signaling in bioanalysis. In specific embodiments, two inorganic luminophores, Tris(2,2′-bipyridyl)osmium(II) bis(hexafluorophosphate) (OsBpy) and Tris(2,2′-bipyridyl)dichlororuthenium(II) hexahydrate (RuBpy), or three organic luminophores 5-Fluorescein isothiocyanate (5-FITC), 5-carboxyrhodamine 6G, succinimidyl ester (5-CR6G, SE), 6-carboxy-X-rhodamine, succinimidyl ester (6-ROX, SE) can be simultaneously entrapped inside silica nanoparticles at controlled ratios, with desirable sizes and required surface functionality. Single-wavelength excitation with multiple emission endows the nanoparticles with optical encoding capability for rapid and high-throughput multiplexed detection.
