Area of Science:

Oncology
Biophysics
Nanotechnology

Background:

Cancer drug resistance is a major obstacle in effective cancer treatment.
Current diagnostic tools for drug resistance are often time-consuming or indirect.

Purpose of the Study:

To develop and validate a rapid, label-free drug susceptibility testing (DST) method using nanomotion technology.
To assess the potential of nanomotion analysis combined with machine learning for classifying drug-sensitive and drug-resistant cancer cells.

Main Methods:

Utilized label-free, real-time nanomotion technology to measure dynamic cellular responses.
Applied supervised machine learning to analyze features extracted from nanomotion signals of colon and ovarian cancer cells treated with doxorubicin.
Evaluated classification accuracy for drug-sensitive and resistant cell lines.

Main Results:

Achieved 90.9% accuracy in distinguishing doxorubicin-treated from untreated colon cancer cells.
Reached 84.6% accuracy in classifying doxorubicin-sensitive and -resistant ovarian cancer cells.
Demonstrated perfect classification of resistant ovarian cancer cells within 4 hours and 15 minutes of drug exposure.

Conclusions:

Nanomotion-based DST offers a direct phenotypic readout, providing a faster, label-free alternative for assessing cancer cell drug response.
This technology holds significant potential for personalized oncology by enabling quicker clinical decisions.
Further research with expanded datasets is needed to improve generalizability for widespread clinical application.
