摘要 | Uniformed NaYF4:Yb3+,Tm3+ nanoparticles were synthesized through solvent thermal method in chloride. PAA-based ligand replace strategies were carried out to introduce free carboxylic acid groups which allowed further conjugation with NH2-containing human IgG. The silicon wafer was modified with rabbit anti-goat IgG by using protein G as "bridge", which contributed to eliminate structural or conformational changes of IgG. Owing to the specific antibody recognition to the antigenic, a simple, rapid, efficient and sensitive immunoassay method was developed. The experimental results demonstrate that there is a very good linear correlation between the upconversion luminescence intensity and the amount of goat anti-human IgG in the range of 5~400 nmol/L. The detection limit is as low as 1.82 nmol/L. Our developed detection system shows excellent detection specificity and sensitivity, which provides a new detection method and platform with wide linear range and high sensitivity for diagnosis of major clinical diseases in the future. 2018, Science Press.
