Cutting edge biomedical devices: bioreactor, stimuli-responsive and intelligent carrier/scaffolds for bioelectronics, drug delivery, imaging, and tissue engineering

 

Integrated bio-edge, one of emerging frontiers in materials science and biomedical studies deals with induced conformational changes in biological structures at macro to nano levels.   The model biochemical reactions have found applications in both analytical science and medical technology. Temperature-, pH-, magneto- and photo-switchable biodevices aim to design, construct and evaluate a new generation of products towards advanced application in fabrication of high-order dignostic devices with switchable bioelectronics and modulated biochemical processing.

Fabrication and design of nanobiosensors

The integration of biological or biologically inspired sensing elements with electronic transducers, which lies at the heart of biosensor technology, promises potential solutions to these multifarious diagnostic challenges. Considerable advances have been made recently in fusing biological sensing modules to electronic devices with the potential to create powerful nanoscaled biosensors. This is a newly emerging supra-disciplinary field with very significant commercial potential in the personalized product healthcare and biopharm sectors. Nanoscaled biosensors have not been exploited or commercialised because of technology deficits, but the diseases and lifestyles that affect our body systems occur first at the nanoscale for example any infection or disease in the body. Progress in this field would make significant contributions to advanced medical technology, bioelectronics, nanomaterials and nanotechnology, and lead to the construction of ultra-sensitive nano aptasensors for early diagnosis of cancers. Specifically, we intend to design/create bio-inspired smart nanosystems to develop novel nano- biosensors with high sensitivity and reproducibility for the diagnosis of various diseases. The aim of project is to develop cutting-edge medical nanodevices for early diagnosis of the diseases by improving the sensitivity and selectivity of sensors on the nanomaterials platform including nanoparticles, nanorods and graphene using range of transduces. The nanodevices could help to improve the efficacy of the treatment by the prognosis and detection of disease in the early stage.

Smart nanotheranostics

Smart nanoscopic theranostic systems incorporate therapeutic agents, molecular targeting and diagnostic imaging capabilities that are emerging as the next generation of multifunctional nanomedicine to improve the therapeutic outcome. In the recent years, functional core-shell technology has become a fundamental tool for theranostic devices. The basic insights of using responsive magnetic nanoparticles as a smart metal core serve as magnetic resonance imaging (MRI) and hyperthermic functions in module. The smart magnetic drug nanocarrier allows cells adhesion, proliferation and differentiation with the triggered drug release and monitoring features.

Molecularly imprinted polymer (MIP) sensors

The molecularly imprinted polymers (MIPs) have attracted much attention due to their multifarious affinity such as in sensors, separations, catalysis, drug delivery and waste water management. MIPs have the ability to mimic biological functions through their three-dimensional cavities with specific size, shape, and functionality for mimetic recognition of target molecules and have already been applied for interesting applications such as the separation and recognition of glucose, cholesterol, hemoglobin, peptides, proteins, antibodies; and DNA. We investigate fabrication and characteriasations MIP sensors for real time monitoring of target biomolecules for example glucose, cholesterol and biomarkers of fetal diseases.
