Chemical analysis using 3D printed glass microfluidics

Additive manufacturing (3D printing) is a disruptive technology that is changing production systems globally.

Analysis of Synthesis Mechanism of Gold Nanoparticles Using Glass Microfluidics

According to LaMer diagram, a clearly separate of nucleation and grows step is required to synthesis of monodisperse nanoparticles. However, a critical mixing time Tc until the growth process is started, is not clear experimentally. In this paper, we prepared gold nanoparticles (GNPs) by liquid-phase reduction using citric acid on microfluidics with different flow rates. From relationship of the diameter of the prepared nanoparticle and the mixing time, Tc for the preparation of monodisperse GNPs was found for the first time.

Hybrid PDMS/glass microfluidics for high resolution imaging and application to sub-wavelength particle trapping

We demonstrate the fabrication of a hybrid PDMS/glass microfluidic layer that can be placed on top of non-transparent samples and allows high-resolution optical microscopy through it.
