A method for detecting crude oil or gas in a drilling sample includes introducing a drilling sample into a sample solution containing nano particles, illuminating the sample solution comprising the drilling sample and the nano particles by a laser beam, collecting light scattered by the drilling sample and the nano particles in the sample solution, obtaining a Raman spectrum from the light scattered by the drilling sample and the nano particles in the sample solution, identifying, in the Raman spectrum, a spectral signature associated with a substance around a predetermined Raman shift, and detecting targeted chemicals correlated with crude oil or gas existence underground from where the drilling sample, based on the spectral signature of the substance in the Raman spectrum.

System and method for detecting oil or gas underground using light scattering spectral analyses

A method for inspecting an edible oil includes obtaining a first Raman spectrum from an edible oil sample, discovering an unhealthy, unsanitary, unsafe, or adulterated content in the edible oil sample in part by the intensity level of the fluorescence background in the first Raman spectrum, introducing the edible oil sample to nano-scale surface structures to allow molecules of the edible oil sample to be adsorbed to the nano-scale surface structures, illuminating the edible oil sample and the nano-scale surface structures by a laser beam, obtaining a second Raman spectrum from light scattered by molecules of the edible oil sample adsorbed to the nano-scale surface structures, and identifying the unhealthy, unsanitary, or unsafe content in the edible oil sample using one or more first spectral signatures in the second Raman spectrum.
