Abstract
A latent solvent-based microfluidic apparatus and method involves laminate bonding of two non-elastomeric, cyclic olefin copolymer (COC) components having opposing surfaces to be bonded, wherein in a contacted state there is at least one interstitial space between the contacted surfaces, applying an organic latent solvent to at least one of the opposing surfaces, wherein the latent solvent is in an inactive state, contacting the two opposing surfaces together, actively removing the latent solvent from the at least one interstitial space; and adjusting a latent solvency parameter to activate the latent solvent, wherein the opposing contacted surfaces become bonded.
