ABSTRACT

The importance of nanotechnology cannot be overemphasized because some traditional imaging approaches do not measure up to patients’ requirements due to limitations and lack of specificity, thus, the need for microimage-based drug delivery, detection, and metastatic ablation. Molecular imaging involves the movement, calibration, visualization, and quantification of specific biological mechanisms at the “tracer level” in living systems. We report on specific nanoparticles (NPs) used (with various potency potentials: quantum dots, gold NPs, copper gadolinium, and fluorescent dyes) as labeling markers and molecules for biological screening.

At the current NPs research advancement rate, contrast product with the necessary attributes can be manufactured for any wanted application. There are promising prospects for improved efficacy, compatibility, detection, and isolation of disease targets. Summarily, nanotechnology will further produce particles that harbor interesting properties, which will eventually be explored in the formulations of novel contrast agents to be used in medical imaging. The combination of nanotechnology modalities (with radiological means: CT, ultrasonography, X-rays, magnetic resonance imaging, positron emission tomography, and single-photon emission computed tomography) and telecommunication will improve the accuracy of the theragnostic procedure, 74which eventually influences healthcare. With the advent of multipurpose NPs (at the nanometer-size-range) undergoing clinical trials, we are ushering in the era of “controlled imaging,” producing a comprehensive, smart, customizable, and specific end-user (radiologist/oncologist/imaging-scientist) advantage. In this chapter, we discussed various conditions and factors when considering the design of NP transducers and expatiated examples of the most developed types and fluorescence techniques
