Molecularly imprinted polymers-aptamer electrochemical sensor based on dual recognition strategy for high sensitivity detection of chloramphenicol

UiO-66/Multiwalled Carbon Nanotube Nanocomposite-Coated Quartz Crystal Microbalance Gas Sensor for Discriminating Amine and Formaldehyde

“…MWCNTs have excellent mechanical, electrical, and chemical properties and abundant functional groups on the surface. 29 In addition, the active groups between UiO-66 and MWCNT are able to interact to form chemical bonds to obtain a stable chemical structure.…”

“…However, in order to improve the adsorption performances toward the target gases, UiO-66 needs to be modified with other materials. MWCNTs have excellent mechanical, electrical, and chemical properties and abundant functional groups on the surface . In addition, the active groups between UiO-66 and MWCNT are able to interact to form chemical bonds to obtain a stable chemical structure.…”

A sensitive sandwich-type electrochemical aptasensing platform based on Ti3C2Tx/MoS2/MWCNT@rGONR composites for simultaneous detection of kanamycin and chloramphenicol in food samples

“…21 Geng et al developed an electrochemical sensor based on the dual recognition strategy of the MIP-aptamer sensor for the highly sensitive detection of chloramphenicol (CAP), which greatly improved the specific recognition ability of the sensor. 22 To our knowledge, the electrochemical aptasensor for multi-antibiotics can possibly be classified into two categories, namely, multi-labels and multi-electrode platforms. By contrast, the strategy of multi-labels can simplify the detection and avoid crossing between different analytes.…”

“…30,31 Geng et al modified a glassy carbon electrode (GCE) with MWCNTs, which could significantly improve the current response of the sensor and hence its sensitivity. 22,32 In addition, MoS 2 quantum dots (QDs), a type of zero-dimensional nanomaterial, with actively catalytic edge sites, high surface area and superior electronic and optical properties, have drawn increasing attention in the field of electrochemical detection. 33,34 In addition to that, Ti 3 C 2 T x has attracted a great deal of attention as a carbon material since it has been reported and gradually used in the construction of sensors and capacitors due to its excellent conductivity and stable structure.…”

A Dual-Recognition Fluorescence Enzyme-Linked Immunosorbent Assay for Specific Detection of Intact Lipid Nanoparticles via a Localized Scaffolding Autocatalytic DNA Circuit Amplifier

“…However, the analysis may be interfered with free PEG when the single recognition element is used to detect i-LNPs . The dual-recognition strategy uses two functional recognition elements to identify the different recognition molecules in a given target, , which can greatly improve the accuracy and specificity of its detection . As for i-LNPs, PEG recognition could be the first capture unit to enrich most i-LNPs and free PEG, and phospholipid membranes could be further used for the recognition of i-LNPs.…”
