Point-of-care prostate-specific antigen (PSA) detection offers faster results for cancer diagnosis and forensic analysis. Novel biosensor technologies are emerging to enable rapid, miniaturized PSA testing outside traditional labs.

Area of Science:

  • Biochemistry
  • Analytical Chemistry
  • Biotechnology

Background:

  • Prostate-specific antigen (PSA) is a crucial biomarker for prostate cancer detection and a forensic marker for semen identification.
  • Current PSA assays rely on centralized laboratory analysis, causing delays and increasing costs.
  • There is a growing need for point-of-care (POC) diagnostic solutions.

Purpose of the Study:

  • To review current and emerging analytical technologies for PSA detection.
  • To highlight the potential of novel biosensor strategies for miniaturized PSA assays.
  • To inform clinicians, patients, and forensic professionals about advancements in PSA testing.

Main Methods:

  • Review of existing literature on PSA detection methods.
  • Analysis of novel biosensor technologies for PSA quantification.

  • Discussion of the advantages of POC testing for PSA.

    • Main Results:

    • Current PSA assays are largely centralized, leading to logistical challenges.
    • Emerging biosensor technologies show promise for rapid, on-site PSA detection.
    • Miniaturization of PSA assays is feasible with advanced biosensor platforms.

    Conclusions:

    • Novel biosensor technologies are poised to revolutionize PSA detection.
    • Point-of-care PSA testing will improve patient management and forensic investigations.
    • Future advancements will focus on sensitive, rapid, and portable PSA detection systems.
