Applications of nanotechnology in biomedicine

Abstract

Nanomedicine is the application of nanotechnology in treatment, diagnosis, monitoring and control of biological systems, and is at the leading-edge of clinical medicine and preclinical research. Increasing attention has been paid to the application of nanotechnology in medicine recently ( Figure 1). Nanotechnology means the control of matter and processes at a nanoscale (1-100 nm) in one or more dimensions [1]. The material and devices operated at the nanoscale usually have different physical properties compared with those at the normal size. Nanomedicine-based approaches have thus an unprecedented potential to better control biological processes and to improve the detection, therapy and prevention of multiple diseases. The applications of nanotechnology and its safety have become the highlight of current biomedical research. This paper focuses on the main nanotechnologies and their biosafety encountered in biomedical research, diagnosis and therapy (Figure 2).

Immobilization of iron oxide nanoparticles within alginate nanogels for enhanced MR imaging applications

“…Nanotechnology has great potential to be utilized in the prevention, diagnosis, and therapy of diseases. [1][2][3] In particular, various nanomaterials have been developed for the early-stage detection of cancer via different imaging techniques. [4][5][6][7][8][9][10] Among the imaging techniques, magnetic resonance (MR) imaging is a powerful, noninvasive imaging technique for cancer diagnosis due to its attractive advantages, including a nonionizing radiation source, tomographic capabilities, and high spatial resolution based on the interactions between contrast agents and the protons of different soft tissues.…”

Development trends of etiological research contents and methods of noncommunicable diseases

“…This transformative development disrupts the traditional fragmented approach of the conventional "single-factor versus single-outcome" paradigm and moves it to the more comprehensive "multifactor versus multi-phenotype" paradigm. This profound shift in perspective expands the scope of research, allowing organisms to be studied holistically and revolutionizing the understanding of life from a simplistic viewpoint to one that acknowledges its inherent complexity [11].…”

Theoretical and Practical Principles on Nanoethics: A Narrative Review Article

“…In addition to its advantages in pharmaceutics, nanomedicine also seeks to provide advanced diagnostic pathology and treatment services at the molecular or even micro-molecular level. Attention to such consequences of nanomedicine is critical since this field of science deals directly with human health (8).…”
