Nanotechnology in healthcare

Nanotechnology is becoming a crucial driving force behind innovation in medicine and healthcare, with a range of advances including nanoscale therapeutics, biosensors, implantable devices, drug delivery systems, and imaging technologies.
Universities also have begun to offer dedicated nanomedicine degree programs (example: MSc program in Nanotechnology for Medicine and Health Care).
A nanotechnology-based system, for instance to eradicate cancer, needs four elements:1) Molecular imaging at the cellular level so that even the slightest overexpressions can be monitored;2) effective molecular targeting after identifying specific surface or nucleic acid markers;3) a technique to kill the cells, that are identified as cancerous based on molecular imaging, simultaneously by photodynamic therapy or drug delivery, and4) a post molecular imaging technique to monitor the therapeutic efficacy.
In the following, we’ll cover these four areas and provide a comprehensive overview of healthcare advances that may be possible through nanotechnology, ranging from fitness monitoring, prevention, diagnosis to therapy, and everything in between.
Fitness Monitoring
When you hear ‘fitness monitoring’ you probably think of the plethora of smartphone apps and the bracelets and wristbands that are on the market. Nanomaterials are going to open new realms of possibility for these monitoring gadgets.
