Since its discovery in year 2004, graphene has demonstrated ground-breaking fundamental science. Yet, graphene-based innovations for societal benefits (such as innovations in energy, environment, agriculture) are still in infancy. Graphene for chemical sensing, in general, has high potential due to possibility in surface area and/or atomic defect density manipulation apart from its high electronic, thermal, and mechanical properties. Manufacturing high quality graphene-based inks with advancing printing technology will pave the way for scalable, flexible and cost-efficient electronic devices that can collectively build a graphene-based IoT platform. Thus, the enabling printed graphene-based device in the detection of molecules like phosphates in the soil (or water, other environments) will revolutionize the field of precision technology. Manufacturing high quality inks is key step needed. In this project we are manufacturing highly conductive and stable graphene inks to study molecular sensing in environment.
