Abstract: Disclosed herein is a nanocomposite comprising a core-shell nanoparticle and a core-shell quantum dot. The core-shell nanoparticle comprises a phosphor core, a shell layer, and a cleavable peptide. The core-shell quantum dot comprises a center core, an intermediate layer, an outer layer, a silica layer, and an arginylglycylaspartic acid (RGD) peptide. The core-shell nanoparticle and the core-shell quantum dot are linked to each other via forming a peptide bond between the cleavable peptide and the RGD peptide. Also disclosed are the uses of the nanocomposite in making a diagnosis of tumors.

Abstract: An electronic candle assembly includes a plurality of electronic simulation candles, a main body supporting the electronic simulation candles, a power supply for supplying power, and a sensor system received in the main body. Each electronic simulating candle includes an illuminating device. The sensor system includes a plurality of sensors, an analog-to-digital convertor, a storage unit, and a processor. The sensors measure the velocity of air current traveling through the illuminating device and outputting the velocity of the air current as an analog electrical signal. The analog-to-digital convertor converts analog electrical signal into a digital signal. The storage unit stores predetermined velocity values and predetermined modes for powering the illuminating device. The processor compares the digital signal with the predetermined velocity and controlling the power supply to power the illuminating device in a predetermined mode.
