Aptamer-Target-Gold Nanoparticle Conjugates for the Quantification of Fumonisin B1

Vicente Antonio Miron-Merida et al.

Summary: The study assessed the performance of two aptamers (40 and 96 nt) in the colorimetric quantification of FB1 through an aptamer-target incubation step followed by the addition of gold nanoparticles (AuNPs) and NaCl. While MgCl2 and Tris-HCl were crucial for aptamer 96 and 40 nt, respectively, the latter was not specific for FB1. Instead, the formation of Aptamer (96 nt)-FB1-AuNP conjugates in MgCl2 exhibited stability to NaCl-induced aggregation at increasing FB1 concentrations. The application of asymmetric flow field-flow fractionation (AF4) allowed for size separation and characterization with a reduction in the limit of detection from 0.002 mu g/mL to 56 fg/mL.

Using Simple- Structured Split Aptamer for Gold Nanoparticlebased Colorimetric Detection of Estradiol

Chia-Chen Chang et al.

Summary: A sensitive colorimetric biosensor for label-free detection of estradiol was developed using a estradiol-specific split aptamer. The sensor showed superior response when a split aptamer with a high free energy of the secondary structure was used, with a detection limit of 6.7 nM.

Advances in Gold Nanoparticles-Based Colorimetric Aptasensors for the Detection of Antibiotics: An Overview of the Past Decade

Qurat Ul Ain Zahra et al.

Summary: Misuse of antibiotics has become a global issue due to its harmful effects on human health. To address the limitations of conventional methods, it is essential to develop fast, simple, sensitive, and reproducible methods for antibiotic detection. Among the recent methods developed, aptasensors stand out for their specificity, sensitivity, and selectivity, particularly due to their combination of aptamer with colorimetric applications of gold nanoparticles.
