Perovskite-gold Shell Composite Nanoprobe for Trimodal Lateral Flow Immunoassay Detection of SARS-CoV-2 Antibodies

XWXin WangZTZhi TongHLHongyu Liu

Key Points

  • The aim is to develop a nanoprobe that enables effective detection of SARS-CoV-2 antibodies using multiple signaling modes.
  • Developed a CsPbBr3@SiO2-Aushell nanoprobe.
  • Conducted a trimodal immunochromatographic assay.
  • Utilized colorimetric, fluorescent, and photothermal signals for detection.
  • Achieved detection of SARS-CoV-2 IgG antibodies.
  • Photothermal mode provided the highest sensitivity.
  • Demonstrated environmental adaptability and internal verification.

Abstract

A CsPbBr3@SiO2-Aushell nanoprobe enables trimodal (colorimetric/fluorescent/photothermal) lateral flow immunochromatographic assay for SARS-CoV-2 IgG detection. This multi-signal approach offers environmental adaptability and internal cross-verification, with the photothermal mode achieving the highest...
