You tin finally put those Lego skills from your childhood to work designing medical tests, thanks to a new project from MIT'south Little Devices Lab. Researchers there have developed a set of modular blocks that you can assemble to run various assays with liquid samples. They can measure blood glucose levels or observe viral infection, and that's just the start. Simply snap them into a frame, add your sample, and wait for the results.

The MIT team designed "Ampli blocks" to address the demand for inexpensive modular testing systems. While it might be possible for a lab to test for a particular viral infection, not all facilities have the necessary equipment to do information technology. Developing portable diagnostic devices tin can brand testing more accessible, just there's little involvement in mass-producing specialized hardware that may simply be used to test modest numbers of people. Ampli blocks have the potential to support a large number of customizable tests without added manufacturing expense.

So far, the squad has designed nigh 40 different color-coded modular blocks. Each one consists of a reusable base of metal or plastic virtually half an inch across forth with a glass cover. A sheet of newspaper or fiberglass is sandwiched nether the glass, and this is where all the chemistry happens. Some of the blocks accept spots where doctors can add their samples, which so diffuse through the paper tabs.

The idea is that you'll link multiple blocks together, allowing your sample to pass through numerous newspaper testing environments. The blocks may take multiple channels with unlike reagents that mix with the sample, sending the fluid off to more blocks. Many of the blocks include antibodies fastened to nanoparticles that detect specific molecules. When a molecule is present in a sample, most blocks respond with a colored reaction. Doctors can fifty-fifty run the aforementioned sample over a block again to enhance the colorful response.

As a proof of concept, researchers combined blocks to bank check for three unlike molecules in a sample, which serves equally a test for isonicotinic acid. That's an indicator of whether or non tuberculosis patients are taking their medication. The team is currently developing blocks that tin can test for man papilloma virus, malaria, Lyme disease, and more. MIT wants to get Ampli blocks into the hands of medical professionals across the world, just they've already been sent to labs in Republic of chile and Nicaragua. The next pace is to set a spin-off company that can manufacture the blocks en masse.
