Peculiarities of Integrating Mechanical Valves in Microfluidic Channels Using Direct Laser Writing

Figure 2

Steps of integrating the polymeric structure into an open glass channel using the hard prepolymer (in our case SZ2080) and immersion objective. (a) Prebake of the material. (b) Integration of functional element into the channel by applying immersion oil onto hard prepolymer. (c) Development. (d) Finished structure.
