项目摘要
The country of Nepal has major issues with the quality of its drinking water. Tools to assess drinking water quality are too expensive and not available. We will address this problem by developing a handheld fluorometer to detect tryptophan-like fluorescence as a proxy for bacterial contamination in drinking water. Our novel design is intrinsically simple and can be made at low cost. The core of the instrument is a high numerical aperture metalens that maximises collection efficiency and that can be made by nanoimprint lithography. The metalens will be designed to be strongly chromatic such that the images for different wavelengths are laterally displaced, such that emitter and detector can be placed next to one another. We will develop a translation pathway for prototype instruments to be made in Nepal for use in local communities.
尼泊尔的饮用水质量存在严重问题。评估饮用水质量的工具太昂贵,而且无法获得。我们将通过开发一种手持式荧光计来解决这个问题,该荧光计可以检测作为饮用水中细菌污染的代表的类荧光。我们的新设计本质上是简单的,可以以低成本制造。该仪器的核心是一个高数值孔径超透镜,最大限度地提高收集效率,可以通过纳米压印光刻。超透镜将被设计为强烈的彩色,使得不同波长的图像横向移位,使得发射器和检测器可以彼此相邻放置。我们将为尼泊尔制造的原型仪器开发翻译途径,供当地社区使用。
