Overview

Experimental study demonstrates single-solvent acetone smoothing and bonding for PMMA microfluidics, indicating a cleanroom-free route for high-strength diagnostic chip fabrication.

Key Points

Develop a simplified, cleanroom-free single-solvent technique using pure acetone to polish rough channel surfaces and bond PMMA microfluidic chips.
Treated laser-ablated polymethyl methacrylate (PMMA) microfluidic channels with controlled pure acetone exposure and thermal conditioning.
Bonded PMMA substrates together using acetone-assisted solvent welding without extra adhesive reagents.
Assessed microchannel optical clarity, minimum feature resolution down to 88 µm × 132 µm, bond strength, and sealing integrity under high centrifugal stress.
Acetone treatment combined with thermal conditioning smoothed rough laser-cut surfaces to achieve optical transparency comparable to bulk PMMA.
Acetone-assisted solvent bonding achieved interface bond strengths up to ~27.3 MPa, approaching PMMA's intrinsic tensile strength.
Sealed microfluidic channels maintained intact geometry down to 88 µm × 132 µm and demonstrated leak-free stability under high centrifugal forces.
