The ultimate aim of the project is to develop a low-cost spectrometer that analyses the samples in the Nanoscale range and to minimise the usage of samples for diagnostic application. The reflection, absorption or transmission phenomenon alters the incident light during the interaction with the sample. A spectrometer measures this change over a range of incident wavelengths of electromagnetic radiation that has interacted with a sample. The light that acts as a source is passed through the sample. The prepared test sample is analysed in order to validate the developed system. Following the test samples, urine is analysed. 10 volunteers were involved as subjects. The light from the sample passes through a slit and then reflected by a collimating mirror. The wavelength of the light from the sample is analysed by Thermino software in the UV and visible range. The input to this software is provided by the webcam. A 1000 lines/mm diffraction grating is utilized to split the light into its constituent wavelength. This is a low-cost system than the available commercial spectrometers used in the laboratory.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
