The electrochemical detection of alpha-feto protein based on novel gold nanoparticles-poly(propylene imine) dendrimer platform is reported. The platform was prepared by co-electrodeposition of gold nanoparticles and generation 3 poly (propylene imine) dendrimer on a glassy carbon electrode. Each modifying step was characterised by cyclic voltammetry and electrochemical impedance spectroscopy. The electrochemical measurements showed that the platform was stable, conducting and exhibited reversible electrochemistry. Results obtained from the electrochemical impedance spectroscopy interrogation in [Fe(CN) 6 3À/4À] redox probe showed a marked reduction in charge transfer resistance (R ct ) after each modification step. The immunosensor was prepared by immobilisation of a probe anti-alpha feto protein (AFP) on the platform for 3 hrs at 35 8C followed by blocking the surface with bovine serum albumin to minimise nonspecific binding. The prepared immunosensor was used to detect AFP over a wide concentration range from 0.005 to 500 ng/mL and detection limits of 0.0022 and 0.00185 ng/ mL were obtained for SWV and EIS measurements respectively. The immunosensor gave good stability over a period of fourteen days when stored at 4 8C.

“…Dong at al. [95] used polyamidoamine dendrimers (PAMAM) and silver-cysteine hybrid nanoribbon (SNR) to prepare CdSe QDS-PAMAM-SNR-Ab for detecting brombuterol in pork and feed. Zhu et al used CdTeQDs-PAMAM-GO-labeled antibody composite to detect brombuterol [96] and used CdSe QDs/PDDA-GN/AuNPslabeled antibody composite to detect ractopamine in pork [97].…”

β2-agonists are a group of synthetic phenylethanolamine compounds which are traditionally used for treating bronchospasm. These compounds can also increase skeletal muscle mass and decrease body fat. The illegal use of β2-agonists in food-producing animals results in residue of β2-agonists in edible tissues and causes adverse health effects in humans. Thus, the detection of β2-agonists at trace level in complex sample matrices is of great importance for monitoring the abuse of β2-agonists. Many methods have been developed to detect β2-agonists. Among them, a variety of antigen–antibody interaction-based techniques have been established to detect β2-agonists in various samples, including animal feed, urine, serum, milk, tissues and hair. In this review, we summarized current achievement in the extraction of β2-agonists from testing samples and detection of β2-agonists using immunological techniques. Future perspectives were briefly discussed.

“…22 CdSe QDs are II B -VI A QDs, which is one of the most popular and studied types of QDs. 23,24 The first CdSe QDs were formed in organic solvents. In 2007, Han 25 developed a new method for the direct synthesis of CdSe QDs in the aqueous phase, which promoted the development of the green and simple synthesis of CdSe QDs.…”
