Spectrophotometric detection of tyrosinase activity based on boronic acid-functionalized gold nanoparticles.
نویسندگان
چکیده
A spectrophotometric method for the detection of tyrosinase activity is developed by utilizing the product-triggered aggregation of boronic acid-functionalized gold nanoparticles. Based on the changes of absorbance in UV-visible spectra, the assay shows extremely high sensitivity and lowered limit of detection of 1 × 10(-10) u mL(-1).

Determination of mercury (II) by spectrophotometric method based on self assembly of gold nanoparticles
Due to the binding of the –COO- group with the mercury (II), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the HAc-NaAc buffer solution. The aggregation of functionalized gold nanoparticles and mercury (II)caused the shift of maximum absorption peak of the UV-Vis spectrum from 520 nm to 609 nm.Based on this principle, a simple spectropho...
متن کاملUse of mercaptophenylboronic acid functionalized gold nanoparticles in a sensitive and selective dynamic light scattering assay for glucose detection in serum.
A highly sensitive dynamic light scattering (DLS) assay for glucose detection without interference from ascorbic acid was demonstrated based on mercaptophenylboronic acid functionalized gold nanoparticles (MPBA-AuNPs). The stable, water-solubility MPBA-AuNPs were synthesized using facile and mild method. In the presence of glucose, specific binding between glucose and boronic acids resulted in ...
