Conclusion:

Designing the best personalized combination therapy requires knowledge that transcends patient-specific genetic and molecular information , as well as basic knowledge of the structure and function of the building blocks of biological (nano) materials and the biological barrier and biological environment that are closest to the treatment site To understanding. On the contrary, in order to make new personalized therapies a reality, the sequence and duration of each treatment and the systematic examination of the resulting local and systemic immune responses to the route of administration becomes crucial.

 

The prospect of developing new equipment, better treatments, and diagnostic tests can ultimately improve patients‘ lives and decipher related underlying biological mechanisms, which makes biomedical engineers excited about their contributions to medicine. More bioengineers should seize the opportunity to collaborate with clinicians and scientists across material science, chemistry, and biology in interdisciplinary institutions . Most of the progress made in the past few years, and this series highlights people‘s hopes and expectations for the prospects of precision medicine today.
