Development of a Nanodrop Shape Analysis Tool for Installation in a Novel Nanodrop Spectrophotometer

The rapid identification of liquid composition is an important task integral to a wide range of industries including medical, pharmaceuticals, petrochemicals, and vinification. To aid in this identification spectroscopy can be utilised, however specialised instrumentation must be developed to deliver quantitative information. A spectrophotometer uses spectral data to identify chemical composition of droplets. However, to accurately perform this function, prior knowledge of the size and shape of the droplet is essential to understand chemical quantity. Whilst image data can be easily captured with a high definition camera, the image analysis to translate images into a relevant region of interest (ROI) and to extract usable data autonomously has proven challenging. Here we report the autonomous detection of nanodrops and extraction of their cartesian co-ordinates facilitating the mathematical approximations that can beget values such as volume, contact angle, rate of absorption of spectra, and the length of light paths within the medium.
