Identification and detection of bioactive compounds in turmeric (Curcuma longa L.) using a gas sensor array based on molecularly imprinted polymer quartz crystal microbalance

Abstract

This study aimed to identify four bioactive compounds in turmeric (Curcuma longa L.) using gas sensor array based on molecularly imprinted polymer-quartz crystal microbalance (MIP-QCM). Four QCM sensors coated with...

Greenificated Molecularly Imprinted Materials for Advanced Applications

“…Thus, to increase the practical value of GMIP‐GSs for the concurrent detection of different gases, four individual GMIP‐GSs have been placed into a sensor chamber in an array format, wherein each GMIP‐GS was responsible for the detection of a single bioactive gas. [ 141 ] The appeal of this strategy stems from the high applicability of the developed sensor for simultaneous gas detection with the desired selectivity and sensitivity, and is not particularly attractive from the greenification point of view.…”

Recent Advances in Quartz Crystal Microbalance Biosensors Based on the Molecular Imprinting Technique for Disease-Related Biomarkers

“…Several methods can be applied to design QCM-based biosensor surfaces for various application areas. The QCM is also a sensitive and universal device for measuring concentrations of various gases (e.g., aldehydes) in the air [77][78][79]. The broad uses of QCM-based biosensors have been referred to in published articles concerning the detection of various molecules, including proteins [80], enzymes [81], peptides [82], drugs [83], vitamins [84], metals [85], pesticides [86], biomarkers [87], antibiotics [88], bacteria [89], alcohols [90], aldehyde [91], furanic compounds [92], etc.…”

A novel quinoline derivative as a highly selective and sensitive fluorescent sensor for Fe3+ detection

“…In recent years, atomic absorption spectrometry, inductively coupled plasma mass spectrometry, inductively coupled plasma spectrometry, ow injection analysis, voltammetry and microbiology have been reported in detection of Fe 3+ , and these methods have disadvantages such as complex preprocessing, burdensome process, high operating costs, limited sensitivity and long analysis time. [7][8][9][10][11][12][13] Therefore, the above methods cannot be utilized as analytical tools for real-time or site inspection of target analytes, which greatly limits their practical application. As an alternative method, uorescence sensors possess the advantages of high sensitivity, strong selectivity, fast response, low cost, real-time analysis and good portability, hence it is of great signicance to design and prepare a simple and efficient uorescence sensor.…”
