Selective determination of trace 17β-estradiol in dairy and meat samples by molecularly imprinted solid-phase extraction and HPLC

Electrochemical sensor for the detection of estradiol based on electropolymerized molecularly imprinted polythioaniline film with signal amplification using gold nanoparticles

“…Thus there is an urge for the development of sensitive and accurate techniques for the detection of 17β-estradiol. The commonly used techniques, such as HPLC [4] or GC/MS [5], are time-consuming and expensive. Electrochemical sensors gained interest lately due to their inherent advantages such as low cost, fast response, ease of use and real-time analysis.…”

Applications of SPE-MIP in the Field of Food Analysis

“…60 Junping et al employed surface imprinted silica gel with enrofloxacin as the template, prepared by sol-gel synthesis, and applied the synthesized materials in the determination of the antibiotics in fish and chicken tissue. Their results indicate high affinity, selectivity, and fast template adsorption/desorption kinetics, the feature most desirable in SPE applications.…”

Electrochemical Sensor Based on Multi‐walled Carbon Nanotube/Gold Nanoparticle Modified Glassy Carbon Electrode for Detection of Estradiol in Environmental Samples

“…Among the methods used to monitor estradiol: HPLC [4,7], surface plasmon resonance [8,9], fluorescence [10], Raman spectroscopy [11] etc., electrochemical techniques offer several advantages, such as short time of analysis, simplicity, high sensitivity and selectivity. In electrochemistry, the use of modified electrodes is very common; recent strategies for estradiol detection include different nanomaterials [12][13][14], molecularly imprinted polymers [3,[15][16][17], and antibodies [18][19][20][21].…”
