ABSTRACT
A complicated set of illnesses known as cancer are responsible for one-third of all morbidity and mortality worldwide. Raman spectroscopy can serve as an in vivo modality for image formation because of its high sensitivity and minimal autofluorescence, which can be enhanced by surface-enhanced Raman scattering (SERS) nanoparticles. Nanoparticles with SERS have been extensively used in biological applications like biomarker identification and image-directed theragnostic. Magnetic Resonance Imaging is a crucial technique for diagnosis in the medical field and is also used as an in vivo imaging technique in the field of diagnostics. Radionuclide imaging is the most widely used imaging technique for molecular imaging. Magnetic nanoparticles are nanomaterials that are enthusiastically being used in several technological utilities such as MRI, site-specific drug delivery, and magnetic hyperthermia. Computed tomography, an imaging technique using X-rays applicable to the whole body, has an X-ray source and a detector array, which are the two main components of this imaging technique.
