Project Summary:
In the present project we shall fabricate and validate a microfluidic device based on dielectrophoresis and optical tweezers capable to characterize and separate cancer cells according to their malignancy potency. Specifically, using a novel fabrication approach, we will develop a compact glass based optoelectric biochip for efficient cell trapping followed by microfluidic separation. The device will provide a complete label-free method of cell separation and consists in creating a double trap due to gradients of electric field amplitude and laser light intensity. The sorted cells can be further used for downstream applications (such as, precision medicine diagnostic by providing specific cell subsets or obtaining specific cell cultures for selection of chemotherapy drugs). The device has the perspective to be integrated into an automated theranostic technology or system to evaluate specific cancer cells types and to sort them in designated groups.
Objectives:
The feasibility of the project is ensured by reaching the following Specific Objectives: O1. Opto-electric characterization of cancer cells with different capacity of malignancy. O2. Identification of homogeneous cancer cell populations with similar OEF. O3. Selection and sorting of cancer cells according to their OEF. O4. Validation of cancer cells separation concept and selection procedure based on OEF.

Rezumat:
In acest proiect, propunem fabricarea si validarea unui dispozitiv microfluidic bazat pe dielectroforeza si penseta laser, capabil sa caracterizeze si sa sorteze celule canceroase in functie de potentialul malign. In particular, printr-o noua abordare de fabricare, vom dezvolta un biocip optoelectric pe baza de sticla pentru trapare celulara urmata de separare prin metode microfluidice. Dispozitivul va putea separa populatii celulare printr-o metoda lipsita complet de marcare chimica, prin crearea unei duble capcane celulare rezultate in urma unui gradient al amplitudinii campului electric si respectiv al intensitatii fasciculului laser. Celulele sortate pot fi apoi utilizate pentru aplicatii diverse (precum, obtinerea unui diagnostic precis prin separarea unor subpopulatii celulare specifice sau obtinerea unor culturi celulare specifice pentru selectia citostaticelor in tratamentul cancerului). Dispozitivul are perspective de a fi integrat intr-o tehnologie sau sistem automatizat de medicina teranostica pentru evaluarea unor tipuri de celule canceroase de interes medical si separarea acestora.
Obiective:
Realizarea proiectului este bazata pe urmatoarele obiective specifice: O1. Caracterizarea opto-electrica a celulelor canceroase in functie de potentialul malign. O2. Identificarea populatiilor celulare omogene cu amprenta optoelectrical similara. O3. Selectia si sortarea celulelor canceroase dupa amprenta optoelectrical. O4. Validarea conceptului de separare a celulelor canceroase si a procedurii de selectie pe baza amprentei opto-electrice.
