Abstract

A method for detecting a molecule in a sample includes applying a first filter to an image at a first wavelength. The method also includes applying a second filter to the image at a second wavelength. The method also includes applying a third filter to the image at a third wavelength. The first, second, and third wavelengths are within a predetermined wavelength range, and wherein first, second, and third wavelengths are different from one another. The method also includes detecting a spectral signature for the molecule in the sample in the image after the first, second, and third filters are applied to the image. The method also includes determining whether the molecule is present in the sample based at least partially upon the detected spectral signature.
