Research Overview_____________________________________________________________________________________

Keywords: NanoBioanalytics, Biomicrodevices, Microencapsulation, Microcapsule-PCR, Biosensors, Layer-by-Layer (LbL).

Biomicrodevices: In an interdisciplinary approach we combine microfabrication, surface chemistry and molecular biology to create novel devices using biomolecules (DNA or proteins) for analytical purpose. The final aim is the full integration of biological materials into microdevice fabrication processes, targeting mass production compatibility.

Encapsulation: By using the Layer-by-Layer (LbL) Technology we are creating core shell materials and smart capsules. The LbL technology allows nanoengineering of surface properties to tailor and incorporate different properties into capsules and nano/microparticles.   

Emerging applications are in medicine, drug delivery, medical diagnostics and environmental monitoring.

Research Highlights

Patent on novel Layer-by-Layer encapsulation technology filed (2007)

Patent on a novel bead based microarray decoding/encoding technology filed (2006)

Breakthrough in Bio-MEMS fabrication technology published: Our group recently published a paper on the full integration of biological molecules (DNA and proteins) into the microfabrication process: Trau D., Jiang J., Sucher J.N., Preservation of the Biofunctionality of DNA and Protein during Microfabrication, Langmuir, 22, 877-881, 2006. For the first time it was demonstrated that e.g. DNA can be immobilized and protected during following microfabrication steps. 

Patents in drug delivery granted: The patents EP1190123 and US6833192, granted in 2002 and 2004, describe the LbL coating of microcrystals with applications in drug delivery and bioanalytics. It is one of the core patent of the startup company Capsulution AG. Capsulution AG was founded by Max-Plank Society Scientist, and is dedicated to drug delivery and smart microcapsules.

Patents in diagnostics granted: The patent EP0968412 and US6686208, granted in 2002 and 2004, describe a device and method to carry out evanescent field excitation based fluorescent immunotests. The technology is used by the company pes-diagnosesysteme in their point-of-care diagnostic products.

Patent on new biolabel method granted: German (DE0010042023C2) and European patents  were granted on a new biolabel method developed in Prof Renneberg's (HKUST) and our research laboratory. The novel biolabel system is described in our publication "Nanoencapsulated Microcrystalline Particles for Superamplified Biochemical Assays" published in Analytical Chemistry, 74 (21), 5480-5486, 2002. The method generates a high signal amplification and has potential applications as a substitute for enzyme labels in diagnostics as well as in field tests. The technology is under commercialization by biognostic AG.
