3D nanomembrane architectures: From lab-in-a-tube systems to micro-biorobotics

Prof. Dr. Oliver G. Schmidt, IFW Dresden


Nanomembranes are thin, flexible, transferable and can be shaped into 3D micro- and nanoarchitectures. This makes them attractive for a broad range of applications and scientific research fields ranging from novel hybrid heterostructure devices to ultra-compact 3D systems both on and off the chip. If nanomembranes are differentially strained they deform themselves and roll-up into tubular structures upon release from their mother substrate. Rolled-up nanomembranes can be exploited to rigorously compact electronic circuitry, energy storage units and novel optical systems. They can also serve as ideal platform to study single cell behaviour in 2D confined systems.

If appropriate materials are chosen, rolled-up tubes act as tiny catalytic jet engines which in the ultimate limit may drive compact multifunctional autonomous systems for medical and environmental applications. If magnetic tubes are combined with flagella-driven sperm cells, such hybrid micro-biorobots offer
new perspectives towards artificial reproduction technologies.
