A new ‘on-chip’ immunoassay device

Professor Yarmash‘s lab at Rutgers University have developed a proof of concept microfluidic device, capable of running multiple immunoassays in parallel. The device allows 32 samples to be assayed simultaneously and multiple analytes can be tested in each sample.

As shown in the diagram below, each sample inlet has a bead trap that contains antibody-conjugated microbeads. These are commercially available, allowing virtually any analyte to be tested. The sample flows over the beads at an optimised rate, allowing the analytes to bind to their specific antibodies. A secondary antibody is added that binds to antibodies complexed to analytes, followed by a fluorescent tag that binds to the secondary antibody. The microbeads are then collected, placed in a 96 well plate, and analysed.

Device layout and assay principle

The authors assayed several proteins from an in vitro supernatant and their results corroborated well with a standard benchtop immunoassay. Compared to the benchtop standard, the device has significantly reduced sample consumption as well as large reductions in microbead and detection antibody consumption. It has comparable sensitivity to the benchtop standard and has a large working range, meaning that analytes present at different concentrations in the sample can be measured simultaneously. In addition to this, it is compatible with commercial reagents and analyte concentration can be quantified. Although previously published devices have addressed some of these characteristics, this the first example where they are combined into one device.

Moving on from their proof-of-concept study, the Yarmash group hopes to develop a device capable of in vivo measurements. One example they give is analysis of cerebrospinal fluid in rats, an important animal model in Alzheimer’s research, where immunoassays are currently limited by the small volumes available.

Reprogrammable microfluidic chips

A microfluidic chip with channels that can be programmed then reset and reconfigured has been developed by scientists from France and Japan.

Water is dispensed into chip reservoirs. By selectively switching on electrodes, water is manipulated to carve out the channels

Water is dispensed into chip reservoirs. By selectively switching on electrodes, water is manipulated to carve out the channels

In recent years, scientists from across of the globe have developed a plethora of microfluidic chips to perform a variety of tasks, from PCR to cell sorting. However, a serious drawback of microfluidic technologies is that each application requires a unique arrangement of inlets, outlets and microchannels, so microfluidic chips are usually specific to one particular purpose. This, combined with the time-consuming and costly manufacturing processes required to construct microfluidic devices, makes the idea of a reprogrammable chip very attractive.
