Abstract

This chapter discusses the applications of various nanomaterials employed in two modalities, that is, therapy and imaging. The concept of theranostics is the combination of both therapeutics and diagnostics in one package for image-guided therapy and also for defining the treatment outcome at an early stage. A more detailed description about the different categories of nanomaterials such as carbon-, polymer-, and metallic-based nanoparticles with regard to their ability to perform the dual modalities is given. Current techniques used for therapy including photothermal therapy and imaging tools such as optical, magnetic resonance imaging, and ultrasound are also described with their respective principles. The basic approaches developed by researchers for these classes of therapies and imaging modalities are also discussed. Current developments in theranostics along with several examples of additional techniques, which hold promise for the future of medicine, are specifically emphasized.

    In this process, first, graphite is converted to graphite oxide by forming hydroxyl or carboxyl groups, covalently bound to a graphite planar carbon network. Then, the compound treats with strong oxidizers such as potassium chlorate and fuming nitric acid, and finally, exposing the oxidized materials to water gives conventional GO [41]. In comparison with graphite, the surface of GO was functionalized with oxygen-based groups contains hydroxyl (-OH), carbonyl (CO), epoxide, carboxylic acid (-COOH) and other oxygenated groups [29,42].

    Due to its tremendous potential, this multifunctional therapeutic approach has gained momentum within the medical community as underlined very recently in the cited reports [43,44]. Due to their special characteristics, nanomaterials offer a plethora of possibilities for cancer theranosis [37,45]. Within all the possibilities, nanomaterials of silica have been largely employed in biomedicine [41,46–52] for different purposes such as imaging (fluorescence and magnetic resonance imaging) [53], therapeutic controlled release of drugs [54–60] or imaging and therapy, as in the case of theranostics [20,48,61–65].
