Area of Science:
- Biophysics
- Cell Biology
- Spectroscopy
Background:
- Raman Tweezers integrates optical trapping with Raman spectroscopy.
- This powerful combination facilitates the spectroscopic analysis of individual cells.
Purpose of the Study:
- To present a universal protocol for analyzing fixed and living single eukaryotic cells using Raman Tweezers.
- To outline essential considerations for constructing a Raman Tweezers system.
Main Methods:
- Utilizes optical trapping to immobilize single cells.
- Employs Raman spectroscopy for label-free chemical fingerprinting of cells.
- Describes a generic protocol applicable to both fixed and live cell analysis.
Main Results:
- Demonstrates the capability of Raman Tweezers for identifying and differentiating various cell types, including healthy and cancerous cells.
- Shows the potential for studying single-cell responses to external stimuli, such as drug interactions.
Conclusions:
