Biogreen Synthesis of Carbon Dots for Biotechnology and Nanomedicine Applications

引用

Nano-Micro Letters 2018年第4期10卷 268-313页

作者： Kok Ken Chan Stephanie Hui Kit Yap Ken-Tye Yong School of Electrical and Electronic Engineering Nanyang Technological University

Over the past decade, carbon dots have ignited a burst of interest in many different fields, including nanomedicine, solar energy, optoelectronics, energy storage,and sensing applications, owing to their excellent photoluminescence properties and the easiness to modify their optical properties through doping and functionalization. In this review, the synthesis, structural and optical properties,as well as photoluminescence mechanisms of carbon dots are first reviewed and summarized. Then, we describe a series of designs for carbon dot-based sensors and the different sensing mechanisms associated with ***, we elaborate on recent research advances on carbon dot-based sensors for the selective and sensitive detection of a wide range of analytes, including heavy metals, cations, anions, biomolecules, biomarkers,nitroaromatic explosives, pollutants, vitamins, and ***, we provide a concluding perspective on the overall status, challenges, and future directions for the use of carbon dots in real-life sensing.

Trends in Ultrasonic Transducer design

Trends in Ultrasonic Transducer Design

引用

2009 9th International Conference on Electronic Measurement & Instruments（ICEMI’2009）

作者： Bernd Henning University of Paderborn EIM-E Measurement Engineering Group

Ultrasonic sensors are widespread in the process industry for example to measure flow, filling level, density or substance concentration in liquid mixtures today. On one side technically high demands are made to the ultrasonic sensors on the other side the production of the ultrasonic sensors has to be more and more cost-efficient. Today, these two contrary demands only can be met by the use of efficient development tools. This contribution describes the state of technology in the field of the computer-assisted ultrasonic transducer development, however, also shows the limits.
