Demonstrator Component of Nanomaterials Characterisation

TSB资助的项目是前景LINK项目的一部分，该项目借鉴了英国皇家学会和皇家工程院关于纳米技术带来的机遇和挑战的报告的开创性工作和建议，为经合组织人造纳米材料工作组（WPMN）描述的纳米材料全球安全评估提供直接贡献Naneum在该项目中的一部分是开发一种原型仪器，用于实时检测和监测工程纳米粒子的背景。开发了一种便携式仪器的原型，能够根据尺寸，浓度，形态和化学性质表征工程纳米粒子。在未来，这些数据将提供一个“指纹”，这将使特定的工程纳米粒子从背景中区分出来。该设备的技术是基于创新技术，以开发基于扩散等效直径的同时测量的颗粒特性的二维/三维矩阵，以及化学敏感的冷凝成核。这些测量将允许仪器被校准以识别纳米颗粒的类型，例如烟灰、碳纳米管、金属、金属氧化物等。

The project funded by TSB was part of the PROSPEcT LINK project which picked up on the seminal work and recommendations of the UK Royal Society & Royal Academy of Engineering report on the opportunities and challenges posed by nanotechnologies , providing a direct contribution to the global safety assessment of nanomaterials described by the OECD Working Party on Manufactured Nanomaterials (WPMN)Naneum’s part in the project was to develop a prototype instrument for real-time detection and monitoring of engineered nanoparticles against background.A prototype of a portable instrument was developed which was capable of characterising Engineered Nanoparticles according to size, concentration, morphology and chemical nature. In future such data will provide a “fingerprint” which will enable specific engineered nanoparticles to be distinguished from background. The technology for the device is based on innovative techniques to develop a two/three dimensional matrix of particle properties based on simultaneous measurement of diffusivity equivalent diameter, and chemically sensitive condensation nucleation. These measurements will allow the instrument to be calibrated to identify types of nanoparticles, e.g. soot, carbon nanotubes, metals, metal oxides etc.
