The problem is that microfluidic devices are not a panacea, they usually behave really badly with some solvents or reagents and especially with polymers work they tend to clog. The transport system has the same issue you need to resuspend, evaporate, quench or other treatments and that's hard to automate especially for viscous or hard samples. ML could assist with the definition of conditions and eventually the interpretation of the analytical data, but not at all with all the physical processing which is where the difficulty really is.
