Nanomaterial-amplified chemiluminescence systems and their applications in bioassays 总被引:1,自引:0,他引:1
Nanomaterial-amplified chemiluminescence (CL) has become a growing area of interest in recent years. We review the development of nanomaterial-amplified CL systems and their applications in bioassays. We mainly focus on nanoparticles (gold, platinum, silver, bimetallic, semiconductor and magnetic). Furthermore, we discuss some critical challenges in this field and possible solutions to overcome these challenges. 相似文献

A 2D neutron detector based on 3 He convertor and MWPC with an active area of 200 mm×200 mm has been successfully designed and fabricated.The detector has been tested with Am/Be neutron source and with collimated neutron beam with the wavelength of =1.37.The best spatial resolution of 1.18 mm(FWHM) and good linearity were obtained.This is in good agreement with theoretical calculations. 相似文献

Studies on the third-harmonic generations in cylindrical quantum dots with an applied electric field
The third-harmonic generation (THG) coefficient for cylinder quantum dots with an applied electric field is theoretically investigated. Using the compact density-matrix approach and the iterative method, we get the analytical expression of the THG coefficient, and the numerical calculations of the typical GaAs/AlAs cylinder quantum dots are presented. The results show that the THG coefficient can reach the magnitude of 10−9 m2/V 2. Apart from the length L and radius R of cylindrical quantum dots, both the parabolic confining potential and an applied electric field can also influence the THG coefficient. 相似文献

A prototype of large-area position sensitive neutron detector was designed and constructed according to the requirements of the Small-Angle Scattering spectrometer of China Spallation Neutron Source(CSNS).The detector was based on the 3He neutron convertor and MWPC with an effective area of 650 mm×650 mm.A prototype was completed and tested with 55Fe X-ray.The high-pressure vessel was designed and constructed with high-strength aluminum alloy.A position resolution of about 4.6mm×2.3 mm(FWHM)and efficiency65%for neutrons with wavelength of 1.8?was determined after the operational gas filled. 相似文献
