Our research activity is divided into four main streams

1) Facile and green synthesis of processable organic and bio-organic colloidal materials; 2) Bio-conducting polymer materials for biosensors and printable bioelectronics; 3) Biomaterials and microcapsules for drug delivery and stem cell regenerative medicine; 4) Microstructured processable conducting polymers for printable supercapacitor and energy storage.

1) Facile and green synthesis of processable organic and bio-organic colloidal materials

This research team has developed several advance methods for the fabrication of various processable colloidal materials ranging from structural protein, enzymes, antibodies, conducting polymers (e.g. polypyrrole and poly 3,4-ethylenedioxythiophene (PEDOT), and recently an advance bio-conducting polymer hybrid materials composed of enzyme and conducting polymers. Our research strategy is focused on facile and green chemistry for the bulk synthesis of processable functional materials with controllable chemical properties and nano/microstructure morphologies. This enables us to design new materials and study theirs synergetic effect on chemistry, morphology and internal structural organization of colloidal materials, which is important for understanding the complex physicochemical phenomena occurring at the nano/microstructured material, as well as utilizing the new materials to explore on applications for biosensing, biomedical and energy storage.

2) Bio-functionalized materials for biosensors and printable bioelectronics

Our research focus is on the development of bio-hybrid conducting polymers, and microparticle modules hetero-structured bioelectronics for printable bioelectrodes, investigate the intrinsic electrical and ionic conductivity of the conducting polymers, hierarchical organization of electrode materials, and understand the signal transduction mechanism at the bio-traducer interfaces. Recently, we developed a new method to synthesize water processable enzyme-hybrid conducting polymer microparticles as printable materials for biosensors construction. For printed bioelectronics, my research strategy is focus on a modular construction of hetero-structured bioelectronic interfaces by using tailored functional “biological microparticles” combined with “transducer microparticles” as modular building blocks. This approach offers high versatility for the design and fabrication of printable bioelectrodes with a variety of forms of inter-particle spatial organization, from layered-structures to more advance bulk hetero-structured architectures with enhanced electrode reaction kinetics. We also explore the deposition of the functional colloidal materials on flexible substrates for printed paper-based and fabric-based device. Our ultimate goal is to combine the classical printed electronics and 3D prototyping to develop fully-printable biosensors and biomedical devices which can be tailored made for personalized healthcare monitoring and treatment.

3) Biomaterials and microcapsules for drug delivery, stem cell regenerative medicine

Our research principle on biomedical application is focus on biocompatibility and green chemistry for the facile fabrication of pure biomaterial-based drug carriers with supramolecular self-assembly and bio-assisted crosslinking approaches. We have initiated a pioneer research on protein-based particle for follicular transdermal drug delivery with Prof. Lademann at Charité Hospital University-Berlin, with focus on new skin diseases treatment via follicular drug delivery, drug storage and controlled drug release, sebaceous gland targeting, and more recently on follicular theranostics (therapy and diagnostics) with multifunctional microparticles composed of sensing and therapeutic agents. Besides, we have collaboration with Prof. Bäumler at the Institute of Transfusion Medicine, Charité Hospital University on fabrication of pure hemoglobin particles as artificial oxygen carrier for be potentially used for transfusion medicine.

Our recent research expanded towards stem cell delivery for regenerative medicine. Cell therapy is one of the most promising areas within regenerative medicine, while its full potential is limited by the rapid loss of introduced therapeutic cells. Our research interest is to design and fabricate biocompatible responsive capsules to improve the delivery efficiency, stem cell survival and controlled release of stem cells to the target tissue using human mesenchymal stroma cells (MSCs) model. We have recently reported using thermo-rheological responsive capsules for time-dependent controlled release of MSCs. With this success, we am moving towards in vivo studies on the therapeutic effect of the encapsulated MSCs in collaboration with Karolinska Institute.

4) Microstructured processable conducting polymers for printable capacitors and energy storage

For energy materials, our research focus is on the development of processable nano/microstructured conducting polymers, understanding the morphology, chemical doping effect, porosity and structural organization of the electrode materials to enhance electrocapactive kinetics, ions transport and ion-exchange processes. The team has developed various processable polypyrrole and PEDOT colloids with controllable nano-scale surface feature and chemical dopants as printable high performance electrode materials with enhanced energy storage capacitance. Our recent direction is to create heterostructured hybrid conducting polymers with synergizing conductivity and capacitance effect for enhance energy storage capacity and cycling stability. To understand the mechanism using advance electrochemistry techniques to distinguish the ionic conductivity and electronic conductivity contributed within the heterostructured hybrid conducting polymers, and investigate the effective ion diffuse length and charge transfer resistance as a measurement of electrode kinetics. Our next step is to fabricate a full supercapacitor device with two electrode components using our developed conducting polymer colloids.
