Davie large groups of people believe that one shot LFDs are a great idea, they will cost more, and have no digital signature. Multi user requires the affimer to bind and then release on command, and for the sensor area to be made appropriately sterile to accept the next sample (perhaps 24hrs latter), else you'll risk false positives and negatives.
To me bind and release is optimal, but tricky, an acid wash perhaps, as affimers are meant to be quite stake, or dual powered laser and burn it off? Maybe that can be done, but it'll require a machine to do it, so a much bigger handheld machine, or you removing your sensor from the machine, where the person before you may have been positive? Or just have mucky hands.
Technical and practical problems abound with multi use, but the question is what other options are there that give answers in seconds, and can digitally record the answer for short term use? I'm seeing nothing, so it may not be optimal, but it'll do the job.
