Recent progress in imaging technology combined with nanomaterials for medical applications

Abstract

The development of medical imaging technology has led to progress in nanomedical diagnosis, prevention, and detection. In this study, the latest applications of single-mode imaging, dual-mode imaging and multimode imaging in nanomedicine are reviewed. Meanwhile, in the single-mode imaging section, several imaging techniques such as magnetic resonance imaging and computed tomography illuminate their respective characteristics and medical applications. In the part of dual-mode imaging, nanoprobes and nanodrug carriers as nanobiotechnology applications, which combined with dual-mode imaging are conducive to the accurate cancer diagnosis and efficient delivery of drugs, respectively. In the application of multimodal imaging, owing to the combination of treatment and multimodal imaging, functional diversity and fewer side effects are obtained. Each section outlines the current utilisation and potential of imaging in nanomedicine, illustrating the potential applications in the future. This review is supposed to provide some ideas for the multifunctional application and accelerate another technical leap of fusion imaging technology in medicine.

Recent Progress in Gas Sensor Based on Nanomaterials

“…Compared with pristine ZnO nanowires, they have higher gas sensing performance, uniquely faster response time. Gas-sensitive properties of this hot electron increase sharply because it captured the hot electron by NO 2 gas easily and accelerates its chemisorption on the surface of zinc oxide [21]. Stimulated by hot electrons, it replaced the adsorption process of NO 2 gas by light-excited holes to understand the absorption process [22].…”

Study on transfer learning-based cross-spectral speckle image reconstruction method

“…With the continuous development of imaging technology, its application domains have been expanding to include medical imaging, material imaging, space detection, security monitoring, and so on [1][2][3][4][5]. However, when an object passes through a scattering medium, the imaging information is degraded, making it difficult to obtain the original image directly.…”
