Microfluidic devices are very useful tools with a wide range of applications including environmental sensing, medical diagnostics, drug discovery, drug delivery, microscale chemical production, combinatorial synthesis and assays and artificial organs. Various microfluidic devices can be designed, fabricated and validated at the Macquarie University node of CNBP, depending on applications. We have one ISO Class 7 clean room for semiconductor processing and device fabrication. Fabricated microdevices can be used by connecting to a three channel outlet pressure controller system. They can also be coupled with flow sensors which offer a range of flow rates depending on your needs.
The clean room contains essential fabrication and testing equipment for processing photoresist, spin coating materials, 3D printing, depositing metals, etching (chemically & plasma) and analysing the results (profiler, microscope and film thickness measurements). Microfluidic devices for various chemical and biological applications can be fabricated here.

Proteomics, Glycomics and Glycoproteomics
MProtein glycosylation and glycoconjugates in general are of particular interest due to their fundamental role in cell function. More than 50% of known human proteins are in fact glycoproteins. Dysfunctions in the glycosylation machinery have been associated with a variety of diseases such as chronic inflammatory conditions, cancer, neurodegenerative and cardiovascular diseases as well as reproduction. Glycosylation is also a crucial factor in bacterial and viral infections and the immune response. This makes glycoconjugates extremely interesting diagnostic, therapeutic and prognostic target molecules. In the CNBP we have developed, applied and pioneered Proteomics, Glycomics and Glycoproteomics technologies and translated this knowledge to discover new glyco-features that can be targeted by nanoparticles for diagnosis and drug delivery.
These proteomics, glycomics and glycoproteomics mass spectrometry-based workflows and technologies are used to capture and unravel the identity, quantity and specific glycosylation features of proteins in health and disease of humans and animals.
Potential Uses and Applications
- Understanding mechanisms of glycan-involvement in pain perception
- Unravelling the glycosylation events around the pathogenesis of arterial plaque
- Determining glycosylation features associated with the success of in vitro fertilisation
- Identifying novel glyco-signatures to increase specificity and sensitivity for early stage cancer detection
- Improve functionalisation of nanoparticles for biological applications
- Discovery of new glycosylation targets for biotherapeutics
- Improved imaging of tissues and cells based on precise location of specific glycan structure mass profiles
