Microfluidic technology free tiny droplets to realize high precision control
by:Transon2021-01-08
Droplet suspended technology refers to the mechanical balance field is constructed, the liquid material stable suspension in the gas phase environment.
Due to the movement state of suspension of material resistance, showing excellent motility.
Suspension technique is applied to the droplets microfluidics technology, realization of microscale aerosols in high precision control, can be applied to biological detection, medical and pharmaceutical analysis, nanometer material synthesis, spectroscopy detection, and many other fields.
At present, the technology of the droplet suspension is still limited by the complex suspension system and special condition of suspension, it is difficult to realize tiny droplets of high precision and high degree of freedom to manipulate.
in the near future, Chen rong, energy and power engineering college of chongqing university, professor, professor liao qiang, professor zhu pye and focal lonpos graduate students is put forward based on the microfluidic technology of light to the suspended droplet control technology, using single-beam realized with 10 -

15 L suspended droplets generated the quantitative level, size and high precision motion control adjustment.
Researchers revealed that local thermal effect leads to & other
The gas phase capture trap & throughout;
The suspended droplet generation and manipulation of the decisive role, and the single bundle focus light as & other;
The baton of light & throughout;
On the labyrinth type grid interface implements the non linear variable motion of suspended droplets and start-stop conversion of high precision control.
The technology also applies to contain a variety of biochemical reagent suspended droplets manipulation.
The researchers hope that through the study of complex material conveying and in-situ reaction and analysis to provide new ideas and new methods.
