Active nanotech-based research from China has yielded several new advancements with wide-ranging applications. Newly developed nanosensors can be used to detect toxic environmental pollutants, such as chromium; novel medical technologies can be leveraged to allow point-of-care testing for clinical diagnosis and drug analysis; and they can even provide sustained and controlled drug release. Accordingly, these new technologies are expected to usher in an era of improved healthcare at the levels of prevention, diagnosis, and treatment.
