TITLE:

Fabrication of acoustofluidics lab-on-a-chip devices via additive manufacturing

KEY WORDS:

Microfluidics, Acoustofluidics and Ultrasound

PAGES: 83
BIG AREA: Ciências Exatas e da Terra
AREA: Física
SUMMARY:

The manipulation of particles or microstructures without contamination, either due to the environment or direct contact is of great interest for studies focused on biotechnology and the development of new drugs and applications aimed at diagnosis. In this context, it is necessary to study techniques that make this process more effective. In recent decades there has been a movement in order to remedy this need. In the present work, we will explore techniques for manufacturing acoustofluidics devices, which combine microfluidics techniques coupled with ultrasonic systems, with this capability, as well as advantages and disadvantages. We will study the physical quantities involved in these devices, and how their behavior affects/implies the aggregated features. We will demonstrate the manufacture of these devices, with project development based on analytical simulation, 3D modeling and manufacturing via additive manufacturing, using a printer with DLP technology based on photopolymerizable resin. This device will be able to levitate and standardize objects or beings of the order of µm, we will evaluate its operation, in addition to indicating pioneering applications for the evaluation of microorganisms such as the causes of leishmaniasis and also Raman spectroscopy, reducing the analysis time, increasing practicality, and amplifying the captured signal through improvements in the focusing system used.
