- based microfluidic point - of - care diagnostic devices

Dipstick and lateral-flow formats have dominated rapid diagnostics over the last three decades. These formats gained popularity in the consumer markets due to their compactness, portability and facile interpretation without external instrumentation. However, lack of quantitation in measurements has challenged the demand of existing assay formats in consumer markets. Recently, paper-based microf...

Dynamics of Bacterial Quorum Sensing in Microfluidic Devices

Figure 1: E. coli cells engineered with the luxI/luxR system and the microfluidic device setup in our experiments [4]. C6-HSL is a specific type of AHL. Quorum sensing is an essential communication mechanism in bacteria. By transmitting small molecules to each other, bacteria can sense their own population and respond accordingly. Coupling such mechanisms with synthetic biology can lead to a wi...

Electrochemical sensing in paper-based microfluidic devices.

This paper describes the fabrication and the performance of microfluidic paper-based electrochemical sensing devices (we call the microfluidic paper-based electrochemical devices, microPEDs). The microPEDs comprise paper-based microfluidic channels patterned by photolithography or wax printing, and electrodes screen-printed from conducting inks (e.g., carbon or Ag/AgCl). We demonstrated that th...

Hydrogel-based reconfigurable components for microfluidic devices.

In situ liquid-phase photopolymerization (LP(3)) has been applied to the field of microfluidics to create components within integrated systems. As an extension of LP(3) technology, we present reconfigurable components that utilize the swelling of hydrogels. These components can be conveniently used to enhance microfluidic functions and applications. In order to utilize the swelling characterist...
