Breakthrough in Artificial Plasma Detection: Lysozyme-Imprinted Surface Plasmon Resonance Chips with Gold Nanoparticles

Strategic Insights

— 1 min read

Researchers at Hacettepe University have made a significant advancement in the detection of lysozyme in artificial plasma, artificial urine, and artificial tear solutions using lysozyme-imprinted surface plasmon resonance (SPR) sensors modified with gold nanoparticles (AuNPs). This innovative approach has the potential to revolutionize the field of biomedicine, enabling the real-time determination of lysozyme in complex biological samples.

Key Takeaways:

  • Researchers prepared lysozyme-imprinted (Lyz-AuNP-MIP) and nonimprinted (AuNP-NIP) SPR sensors modified with gold nanoparticles (AuNPs) for signal amplification and real-time determination of lysozymes.
  • The surface morphology of the prepared SPR sensors was characterized by atomic force microscopy and contact angle measurements, demonstrating the effectiveness of the AuNPs in enhancing the signal.
  • The researchers conducted kinetic studies using lysozyme solutions and artificial plasma, artificial urine, and artificial tear prepared from 0.01-500 mg/mL concentrations, achieving a limit of detection and limit of quantification of 0.008 mg/mL and 0.026 mg/mL, respectively.
  • Competitive agents such as myoglobin and hemoglobin were used to demonstrate the selectivity of Lyz-AuNP-MIP and AuNP-NIP SPR sensors.
  • The researchers optimized the experimental studies for lysozyme determination and achieved recoveries of approximately 99% in artificial plasma, artificial urine, and artificial tear solutions.
