Abstract: Embodiments of a computing device and methods of providing a cancer assessment for a patient are described. The method involves isolating a volume of a fluid from a fluid sample of the patient, the volume of fluid including at least one biomarker; adding at least a portion of the volume of fluid to a nanosensor comprising nanoparticles configured to capture the at least one biomarker and amplify signals emitted by the at least one biomarker during Raman spectroscopy; performing Raman spectroscopy on the volume of fluid on the nanosensor to produce a sample Raman spectrum having amplified signals indicating the presence of the at least one biomarker on the nanosensor; processing the sample Raman spectrum using data from template Raman spectra from known cancer samples; and based on the detected one or more cancer characteristics, providing the cancer assessment of the patient.
