Postpartum breast cancer (PPBC), diagnosed within 5–10 years after childbirth, is an aggressive subtype with poor outcomes and limited early detection methods. This project aims to develop organic electrochemical transistors (OECTs) using specially designed polymers that can detect CD44-positive breast cancer stem cells in breast milk. These biosensors offer a non-invasive, real-time method for identifying therapy-resistant cancer cells that often drive recurrence. By combining advanced polymer chemistry and bioelectronics, the team hopes to overcome current imaging challenges and improve diagnosis in postpartum patients.

This research lays the groundwork for a non-invasive, highly selective biosensor to improve early detection of postpartum breast cancer. The goal is to enhance personalized care and diagnostic accuracy for young mothers.
