Microfluidic procedures are made cumbersome and laborious by external connectors, tubing, and pumps. So-called 'finger-actuated’ devices first introduced by Qiu et al in 2009 allow easy and intuitive operation without the need for pipetting ....2/n

this chip looks pretty interesting 👇👇

Here is the full on-chip assay video of our recently developed #fingeractuated blood lysate preparation device. How cool is that?

Many clever ideas for microfluidic sample-to-chip interfacing, sample processing, and reagent storage and release that will be of interest for point-of-care diagnostics

As promised, here are more details about the 'AirCap' feature, a finger-actuated #microfluidic pump that enables complete emptying of a 130 uL chamber in a single stroke. 🧵within a🧵! Slow-mo 📽️at the end Let's start by the AirCap basic principles:

Here are the AirCap features. As previously explained, this is actually the protection cap of disposable vape - nice re-use, but it would be good for people to make their own - anyone cares to print this in a flexible material for us to try? Vittorio Saggiomo (@[email protected]) or anyone else?

It's worth mentioning that previous finger-pumps work really well but are complex to manufacture and have only very small stroke volume, typically in the order of 10 uL or so. The great thing about this one is that it can empty a large chamber in a single stroke.

Slow-mo of AirCap in use. Please cite biorxiv.org/content/10.110… if you use this before the peer-reviewed paper is out

Vittorio Saggiomo (@[email protected]) Md Ehtashamul Haque So here's the deal: anyone sending us printed or cast AirCaps for us to test (replacing the e-cig vape source), will get some finger-actuated cards in return. Details to be sorted in DMs or emails😊

Breaking News! 📢🚨 Paper accepted in Lab on a Chip pending minor revisions! Well done Md Ehtashamul Haque hard work paying off!! One reviewer accepted with no revision 🥹 Thank you to the community for the great response, looking forward to testing printed Aircaps!

Thank you Nikolay Tumanov .. eager to test them with our device

The simplicity of our recently developed #fingeractuated #microfluidic device

I really loved this idea of using the z resolution of a 3D printer to develop this microfluidic cell sorting platform. It's so cool!
