Abstract:
Nanomaterials have shown potential for high-performance functional materials especially in emerging flexible and wearable biomedical and health applications. Structuring of  nanomaterials, including atomically-thin two-dimensional (2D) materials (e.g. graphene) and combining 2D materials with conventional materials such as metals and polymers can enable new functionalities and high performance by engineering exceptional and outstanding mechanical, electrical, and optical properties. In my talk, I will discuss how engineering structures of 2D atomic-layered materials allows for the enhancement of material properties and creating of new functionalities. I will introduce a mechanical manufacturing approach, which allows large-scale, uniform nanostructures with 2D atomic layers and enables mechanical stretch ability and strain-tunable sensing for flexible optoelectronic devices. I will also discuss how multi-dimensional hybrid nanomaterials combining three-dimensional graphene and metallic nanoparticles can be produced in large scale with low production cost by transient laser photothermal processing. I will highlight the potential of the multi-dimensional nanohybrid structured materials in biomedical health applications.
