Advanced Progress of Nano-Based Delivery System for Bioimaging

Nanotechnology has been developing with the development of technology and has made great progress especially in the field of the development of biomedical engineering nanoparticles. Biological imaging plays an important role in medical research. Through biological imaging technology, researchers can intuitively observe the structural and functional changes of organisms at the microscopic level, so as to understand the mechanism of life activities. However, the current biological imaging technology, especially the traditional radioactive material imaging method, has problems such as potential safety hazards and poor imaging effect, which limits its wide application in clinical and scientific research. To address these challenges, research has turned to the field of nanotechnology to explore its potential advantages in bioimaging. Nanotechnology has unique physical and chemical properties. Nano-based bioimaging methods not only improve imaging resolution and sensitivity but also enhance biocompatibility and reduce potential hazards to organisms. This article details the application of various types of nanotechnology, such as liposomes, nanoparticles, and quantum dots, in biological imaging and the remarkable results achieved. These nano-imaging technologies not only realize the fine imaging of cells, tissues and even the whole organism, but also provide strong support for early diagnosis and precision treatment of diseases. This review introduces the applications and effects of different types of nanotechnology in bioimaging, explores the challenges and prospects of nanotechnology in bioimaging, and reveals the current development of bioimaging technology based on nanotechnology.
