Modular microfluidics device
We designed a modular microfluidics device based on acrylic and glass tapered capillary. This modular device could be assembled in a very short time and reusable.

Hollow microfibers with
straight/helical channel
I developed a double co-axial microfluidic device and discussed its flow-control method, e.g., the flow rates and liquid composition of every channel. As a result, I can fabricate hollow fiber with size and shape (straight or helical inner channel) on demand.

Flow connector for
micro-scale tube
In order to facilitate continuous perfusion in the micron-level inner tube via the same device, I proposed a seamless flow connector on the end of the newly formed hollow microfiber using the flow mode “Extraction”.

Three-layer vessel structure
with nutrient vessel
embedded in the tubular wall
This microfluidic device was modified into a 3D printing nozzle that simultaneously controlled three different cells' suspensions. Subsequently, hybrid hollow microfibers were directionally arranged along an auxiliary collecting roller.
