Attogram per milliliter detection of prostate cancer biomarker using polymer dots-based electrolyte-gated organic field-effect transistor

Key Points

• Detection of a prostate cancer biomarker achieved at attogram per milliliter levels, facilitating early diagnosis.
• The polymer dots enhance the sensitivity of the organic field-effect transistor, achieving robust detection.
• Electrolyte-gated organic field-effect transistor technology was employed to amplify signal detection.
• Further clinical validation is needed to support findings and ensure reliability in diagnostic settings.
