Can micro-robots be used to more precisely treat bacterial infections?


– We human beings always have the desire to make something to replicate ourself or the outside world. For example, a few hundred years ago we started to make sculptures and then about 60 or 70 years ago we started to make useful
machines which mimic ourself. (quiet music) But if we really look
at the biologic kingdom, there’s something that’s extremely small, extremely smart, it can do a lot of jobs, but it is on a scale we are not good at, which is the micro and the nano scale. For example, the white blood cell. They can move around and
hang bacteria in passages to make your health healthy. So this is something that motivated me to think about it. Is there any way we can build machines which mimic the white blood cell which can move around your body in order to make you healthy? During my graduate study, I invented a set of micro-robots which could move by a
lot of different methods and, particularly, I
invented the micro-robots which can move in gastric fluid. So the specific application what I did is that I loaded antibiotics which is used to treat bacteria infection on these micro-robots. So once this antibiotics
loaded the micro-robots entered the stomach, they can react with gastric fluid, they can move around in the
chute to the stomach lining which improves the retention
of this drug in your body. In this case, it became proved
through therapeutic efficacy and it killed bacteria
six times more efficient than conventional treatment. So by doing so, we can get rid
of the high dosage medication and also we can reduce
the use of antibiotics. And in the future, we envision that a lot of these micro-robots will be used in many parts of your body to treat disease with high precision and minimal side effect.
