Nanomaterials and nanotechnology have been rapidly developed and widely applied in antimicrobial, biosensors, nanomedicine, nano-electronic technology, reinforcement, water treatment, and so on. However, there are also many problems and challenges during using and developing nanomaterials and nanotechnology. Are they secure enough for the health of human beings? Do they cause the environmental pollution? And how can we sustainably develop nanomaterial and nanotechnology? In this review, we introduced the applications, potential threats and hazards, and development and prospect of nanomaterial and nanotechnology.
