Background:

Conventional cell culture and analysis methods can be cumbersome and induce cellular stress.
There is a need for integrated platforms that allow for real-time, non-invasive monitoring of cells under controlled conditions.

Purpose of the Study:

To develop and validate a miniaturized, user-friendly microfluidic platform for long-term cell culture and analysis.
To enable simultaneous optical imaging and Raman spectroscopy of cells in vitro.
To assess the platform's capability in detecting cellular damage induced by oxidative stress.

Main Methods:

Integration of a mini-incubator with a microfluidic device for controlled cell culture.
Utilizing a gravity-driven flow system for passive medium exchange.
Employing Raman spectroscopy and optical microscopy for non-invasive cell analysis.
Inducing oxidative stress using hydrogen peroxide treatment in tumoral cell lines.

Main Results:

Successful adhesion and proliferation of tumoral cells within the microfluidic device.
Demonstrated capability for real-time optical monitoring and Raman spectroscopic analysis.
Discrimination of spectral changes in DNA backbone and cell membranes due to reactive oxygen species (ROS) activity.
Identification of specific Raman bands correlating with DNA damage, protein synthesis deterioration, and membrane repair mechanisms.

Conclusions:

The developed microfluidic platform supports long-term cell culture with minimal stress.
The platform facilitates simultaneous optical and Raman analysis, providing insights into cellular responses to oxidative stress.
This integrated system offers a promising alternative to conventional cell culturing and analysis techniques, particularly for studying cellular damage and repair mechanisms non-invasively.
