BIOTECHNOL BIOPROC E 2022; 27:202-212. [PMID: 35474695 PMCID: PMC9026004 DOI: 10.1007/s12257-021-0220-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 09/16/2021] [Accepted: 09/19/2021] [Indexed: 11/28/2022]
Abstract
This study aimed to develop a label-free fluorescent aptasensor for the detection of diazinon (DZN) on a cyclic olefin copolymer (COC) substrate. The aptasensor design was based on rolling circle amplification (RCA) technology and the use of self-assembled copper nanoparticles (CuNPs). A dual-function (DF) probe, capable of binding to circular DNA and an aptamer, was designed and immobilized on a COC-bottom 96-well plate. An aptamer was used for selective recognition of DZN, and the specific site of the aptamer that strongly reacted with DZN was successfully identified using circular dichroism (CD) analysis. In presence of DZN, the aptamer and DZN formed a strong complex, thus providing an opportunity for hybridization of the DF probe and circular DNA, thereby initiating an RCA reaction. Repetitive poly thymine (T) sequence with a length of 30-mer, generated in the RCA reaction, served as a template for the synthesis of fluorescent copper nanoparticles, emitting an orange fluorescence signal (at approximately 620 nm) proportional to the amount of RCA product, within 10 min under UV irradiation. The CuNP fluorescence was imaged and quantified using an image analysis software. A linear correlation of the fluorescence signal was confirmed in the DZN concentration range of 0.1–3 ppm, with a detection limit of 0.15 ppm. Adoption of a label-free detection method, utilizing RCA and fluorescent CuNPs on COC substrates, reduced the need for complex equipment and requirements for DZN analysis, thereby representing a simple and rapid sensing method circumventing the limitations of current complex and labor-intensive methods.

Overview of a bioremediation tool: organophosphorus hydrolase and its significant application in the food, environmental, and therapy fields. Appl Microbiol Biotechnol 2021; 105:8241-8253. [PMID: 34665276 DOI: 10.1007/s00253-021-11633-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 10/01/2021] [Accepted: 10/03/2021] [Indexed: 12/14/2022]
Abstract
In the past decades, the organophosphorus compounds had been widely used in the environment and food industries as pesticides. Owing to the life-threatening and long-lasting problems of organophosphorus insecticide (OPs), an effective detection and removal of OPs have garnered growing attention both in the scientific and practical fields in recent years. Bacterial organophosphorus hydrolases (OPHs) have been extensively studied due to their high specific activity against OPs. OPH could efficiently hydrolyze a broad range of substrates both including the OP pesticides and some nerve agents, suggesting a great potential for the remediation of OPs. In this review, the microbial identification, molecular modification, and practical application of OPHs were comprehensively discussed.Key points• Microbial OPH is a significant bioremediation tool against OPs.• Identification and molecular modification of OPH was discussed in detail.• The applications of OPH in food, environmental, and therapy fields are presented.

Easy-to-use and reliable absorbance-based MPH-GST biosensor for the detection of methyl parathion pesticide. ACTA ACUST UNITED AC 2020; 27:e00495. [PMID: 32642456 PMCID: PMC7334298 DOI: 10.1016/j.btre.2020.e00495] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 06/02/2020] [Accepted: 06/22/2020] [Indexed: 01/08/2023]
Abstract
Simple, inexpensive, high-efficiency absorbance-based OP biosensor was fabricated. Covalently immobilized methyl parathion hydrolase was used as a biomolecule. The biosensor can be used at room temperature for 100 rounds repetitively. The biosensor could detect MP with the detection limit of 0.1 μM. The biosensor showed high reliability for detecting MP in real samples.
Due to high contamination of organophosphate (OP) insecticides in agricultural products and the environment, efficient and convenient devices for their monitoring are necessary. Here, a simple, inexpensive, efficient, and easy-to-use absorbance-based biosensor was fabricated utilizing recombinant methyl parathion hydrolase fused with glutathione-S-transferase (MPH-GST), covalently immobilized onto a chitosan film-coated polystyrene microplate, for the detection of methyl parathion (MP) as a representative of OPs. Having been connected to the transducer system designed to work through an Arduino microcontroller, the biosensor could detect MP as efficiently as the conventional methods, with the detection limit of 0.1 μM, the lowest value ever reported for this method. It was stable at 25 °C for 30 days, could function 100 rounds repetitively, and yielded high recovery with real samples. Hence, this simply designed MPH-GST biosensor could be an easy and inexpensive alternative for efficient OP screening at site to help control its contamination.
