Ken Halvorsen @halvorsenlab.bsky.social · 01/09/2026Good point, we did not do this though I do remember discussing it at some point. I can't recall why not, or if it was attempted and abandoned for this project. This would be better to ask our MD collaborators (Chen & Vangaveti labs) who did the modeling. Thanks for your interest in the work :) 110

Ken Halvorsen @halvorsenlab.bsky.social · 14/03/2026MIRA has been terrific for my lab but I am squarely in the "all eggs in one basket" category as I apply for my second renewal during uncertain times. 😬 010
Ken Halvorsen @halvorsenlab.bsky.social · 26/02/2026Haha I'm one of these people, though I acknowledge I'm clearly in the minority. Google scholar "cite" with copy-paste is my preferred method if I'm doing it myself. 010
Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026We mostly just got rid of all the stuff we didn’t need from a standard gel setup. Turns out you don’t need >200 mL of running buffer, or >100 V between electrodes, or >$1k to spend on a gel box – you just need a 3D printer and a different design. How satisfying! 000
Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026With a range of designs, we resolved on/off nanoswitches in ~1 minute at 75 volts or in ~45 minutes at 8 volts. We also showed that we could image the gel with a cell phone camera, LED flashlight, and filter paper... 100
Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026One huge advantage of smaller box is the same voltage gives a larger electric field (closer electrodes), enabling either lower voltage operation or faster separation at the same voltage. 3D printing allowed us to quickly test various inter-electrode distances... 110
Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026Side note for those interested in electrophoresis – this design is cheap and easy! Prints in <1 hour on a dual-extruder printer for ~30 cents of material (>1000x less than any gel box from lab supply stores). We also printed replacement gel combs which performed identically to the $50+ combs... 100
Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026Postdoc Lifeng Zhou 3D printed mini boxes and added wire electrodes with early encouraging results that we could eliminate much of the gel apparatus. Later Andrew Hayden found conductive filament, and 3D printed the whole gel box with electrodes. It works as well as our conventional gel system! 100
Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026It started because: 1) we noticed that typical gel equipment was overkill for our application, and 2) we heard criticisms that DNA nanoswitch sensing could never become “point of care” due to reliance on electrophoresis. This combined two passions - design minimalism and proving critics wrong :) 100
Ken Halvorsen @halvorsenlab.bsky.social · 27/01/2026This dates to ~2019 - we asked whether we could redesign gel electrophoresis to better suit our DNA nanoswitch sensors (which shift migration based on molecular detection). We ended up with a fully 3D printed mini-gel costing ~30 cents, operable with batteries, and capable of detection in minutes… 100
