**5. Applications of graphene based hybrids**

Graphene based hybrids have a major role in food microbiology, where the microbes are applied on the Nano-scale level to prevent the packaged food from being rotten and it gives the food a long lifetime. Graphene based hybrids have been used in nano robotics. Nano-robotics is an emerging technology that creates machines or robots whose components are at or near the scale of a nanometer. Moreover, graphene based hybrids have been extensively used in drug delivery, food sciences, nano-optics, nano-energy, photo-voltaic, nano-chips, light-weight mechanical and electronics applications. Recently, Billions of dollars are being spent to research the use of nano-materials for the detection and treatment of diseases like chemotherapy and the manufacturing of minuscule sensors. Miniscule sensors can be injected into our body which can monitor our vitals even more closely than a doctor. Graphene based sensors are one of prominent addition in recent times for detections of diseases. Graphene based hybrid sensors can be manufactured in large quantities at a very low cost. These sensors are used to monitor the health of frameworks such as bridges and nuclear reactors as well as in the industries.

In addition, graphene-polymers based materials are trying to replace conventional materials in food packaging. And Nano-sensors are also developed to detect the presence of contaminants and dirt in the food particles respectively.

Nanotechnology provides a range of options to improve food quality and helps in improving food quality taste. Nano-encapsulation techniques have been used to improve the flavor of food.
