Lab-in-a-tube and Nanorobotic biosensors (LT-NRBS)
Date du début: 1 janv. 2013, Date de fin: 31 déc. 2017 PROJET  TERMINÉ 

The goal of this project is to develop new types of biosensors based on two different approaches: (i) a new bioanalytic microsystem platform for cell growth, manipulation and analysis using on-chip integrated microtubes and (ii) the use of synthetic self-propelled nanomotors for bioanalytical and biosensing applications. Based on the novel “Lab-in-a-tube” concept, we will design a multifunctional device for the capturing, growth and sensing of single cell behaviours inside “glass” microtubes to be employed for diverse biological applications. We will decorate the walls of the microtubes with proteins from the extracellular matrix enabling the long-term study of cellular changes such as mitosis time, spindle reorientation, DNA damage and cellular differentiation. These microtubes are fabricated by the well-established rolled-up nanotechnology developed in the host institution. Moreover, the multifunctionality of the “Lab-in-a-tube” platform will be extended by integrating different modules into a single microtubular unit, bringing up several applications such as optofluidics(bio)sensors, electrodes for electrochemical control and sensing, and magnetic biodetection.At the IIN institute in IFW Dresden, we are pioneers on the fabrication of catalytic microjet engines (microbots) and their use for transporting different kinds of objects in vitro into a fluid. The remote controlled motion of these autonomous microbots and the transport of microobjects and cells to specific targets within lab-on-a-chip systems is possible. Their walls can be biofunctionalized with enzymes, antibodies or DNA, the catalytic microbots representing a novel and unique tool for biosensing, environmental and biomedical applications. Our next step is to use biocompatible fuels to propel these microbots with the final aim of transporting and delivering drugs in vivo.The separation of cancer cells, bacteria and other biomaterials to build up new tissues or to replace disease cells are also aimed.
