Chemistry and properties of nanocrystals of different shapes.

Recent developments have greatly improved the sensitivity of optical sensors based on metal nanoparticle arrays and single nanoparticles. We introduce the localized surface plasmon resonance (LSPR) sensor and describe how its exquisite sensitivity to size, shape and environment can be harnessed to detect molecular binding events and changes in molecular conformation. We then describe recent progress in three areas representing the most significant challenges: pushing sensitivity towards the single-molecule detection limit, combining LSPR with complementary molecular identification techniques such as surface-enhanced Raman spectroscopy, and practical development of sensors and instrumentation for routine use and high-throughput detection. This review highlights several exceptionally promising research directions and discusses how diverse applications of plasmonic nanoparticles can be integrated in the near future.

Neural network modeling of the dynamic inactivation of probiotics during single droplet drying for improved cell viability

Five main risk factors of fintech lending enterprises are empirically analysed by using the duration analysis model. The main findings are: Technology does not cause a significant increase in enterprise risk, the main reason is that although technology brings new types of risk, namely, technical risk, but it eliminates the human errors and moral hazards in a certain extent. There is debate on the role of regulatory policy on corporate risk, ‘market failure theory’ and ‘regulatory failure theory’, the empirical results show that the institutionalization of regulatory is more conducive to reducing risk than the frequently issuing ‘new regulatory policies’. As for the debate about whether large or small enterprises carry greater risks, the empirical evidence shows that the failure risks of large enterprises are only 79% of the risks of small enterprise. Another important finding is that the risks of listed companies or venture capital-controlled enterprises are far less than that of private enterprises, which suggests that the institution is very important to reduce risk.
