Innovating Biomanufacturing of the Future

The Biomanufacturing Devices group innovates solutions for continuous biomanufacturing and the data-driven future. We leverage on microfluidic, sensor and automation technologies to achieve a smaller footprint by eliminating holding steps or GMP space requirements, as well as to enable enclosed sampling, real-time analysis and adaptive control. We can accelerate the process development feedback loop between biological characterisation and product or bioprocess designs, enabling future ready, high throughput bioprocessing research. Our team hopes to develop a microfluidic toolbox with a multitude of microfluidic tools, that can provide industrial level functionality at the laboratory scale. We also hope to deliver a wide-ranging impact in biologics, cell/gene therapy manufacturing as well as medtech/healthtech research.

Focus Areas

  • Clog-free Perfusion Filter Systems to reduce cost of goods (CoGs) for cell culture-based products and cell manufacturing
  • Microfluidic innovations which accelerate upstream process development in continuous biomanufacturing
  • Flexible, feedback-controlled microfluidics-enabled automation for in-line or at-line process analytical technologies and predictive analytics towards Industry 4.0

Our Technologies

Membrane-free Microfilter

Zero Clogging High Density Cell Filter – uVisflo

Our proprietary in-house cell retention filter, uVisflo, overcomes the problem of biofouling and clogging that often occurs in traditional membrane-based filters, especially for high density cultures used in biomanufacturing. Our membrane-free  technology has the has the following capabilities:

  • Clog-free – No biofouling.
  • Ultra-high density – Up to 100 million cells/mL.
  • Enhances viability – Increase viability by 5% of bioreactor for every filtration operation.


Integrated Microfluidic Modules

Tube-free Microfluidic Switchboards

We have combined several microfluidic components with programmable digital pneumatics, to achieve precise switching and controlled fluidic flows. These microfluidic switchboards can be further equipped with novel biosensors, creating a fully integrated platform for continuous processing. The integrated platform offers the following advantages:

  • Minimal sample volumes and tube-free operations.
  • High throughput and programmability.
  • Miniaturization of multiple lab scale functionalities into microfluidic devices.
  • High precision switching, control and sensitivity.
  • Real-time data monitoring to ensure critical process parameters (CPPs) for in-process learning and automated online processes.
  • Integrated microfluidic modules for functional versatility, diversity and optimal adaptive control.
