Delivery of nutraceuticals using nanotechnology

The editorial on delivery of nutraceuticals using nanotechnology is very interesting.[1] As noted, successful formulation of new nanosubstance is the hope. However, the effectiveness and safety is still the consideration.[1,2] The concern is further testing of the new nano‑product. A good testing system is needed. Generally in vitro experiment might be convenient but it cannot answer the question. There are many concerns of the nano‑products. The in vivo stability of the new product must be studied. Indeed, the nanosubstance is usually highly sensitive and aggregation can easily occur.
