“…Phthalates have been frequently used as additives in polymer materials, which are widely used in plastics because they improve the plasticity, flow, and durability of plastic materials. − The added phthalates into plastics can dissolve, migrate, and volatilize, eventually entering the ecosystem, which can harm human health and the environment. − As a widely used phthalate plasticizer, the annual production of di(2-ethylhexyl) phthalate (DEHP) has exceeded 2 million tons . Recent surveys indicate that food and beverages are the primary sources of human exposure to DEHP, and elevated concentrations of DEHP are frequently detected in various types of waters, including surface water, stormwater, sediment, soil, treated and untreated wastewater, and sewage sludge from full-scale sewage treatment plants. , DEHP exposure raises concerns about endocrine, reproductive, and neurological dysfunction, as well as acquired diseases such as cancer, allergies, and gender-specific birth defects. , Therefore, the rapid and sensitive detection of DEHP is of great importance.…”

Organic electrochemical transistors with signal amplification and good stability are expected to play a more important role in the detection of environmental pollutants. However, the bias voltage at the gate may have an effect on the activity of vulnerable biomolecules. In this work, a novel organic photoelectrochemical transistor (OPECT) aptamer biosensor was developed for di(2-ethylhexyl) phthalate (DEHP) detection by combining photoelectrochemical analysis with an organic electrochemical transistor, where MXene/Bi 2 S 3 /CdIn 2 S 4 was employed as a photoactive material, target-dependent DNA hybridization chain reaction was used as a signal amplification unit, and Ru(NH 3 ) 63+ was selected as a signal enhancement molecule. The poly(3,4ethylenedioxythiophene):poly(styrenesulfonate)-based OPECT biosensor modulated by the MXene/Bi 2 S 3 /CdIn 2 S 4 photosensitive material achieved a high current gain of nearly a thousand times at zero bias voltage. The developed signal-on OPECT sensing platform realized sensitive and specific detection of DEHP, with a detection range of 1−200 pM and a minimum detection limit of 0.24 pM under optimized experimental conditions, and its application to real water samples was also evaluated with satisfactory results. Hence, the construction of this OPECT biosensing platform not only provides a promising tool for the detection of DEHP but also reveals the great potential of the OPECT application for the detection of other environmental toxins.

“…Traditional electrochemical sensors are unable to specifically identify DBP. However, the combination of molecular imprinting technology and electrochemical sensors can achieve enhanced sensitivity, specificity, simplicity, and the rapid detection of target molecules [ 27 ]. Molecular imprinting technology involves polymerizing the template molecule with the appropriate functional monomer to obtain a polymer, and then the template molecule is eluted by a certain method to create cavities and re-recognition sites within the polymer that are complementary to the template molecular space.…”

Development of an efficient technique for accurate and sensitive dibutyl phthalate (DBP) determination is crucial for food safety and environment protection. An ultrasensitive molecularly imprinted polymers (MIP) voltammetric sensor was herein engineered for the specific determination of DBP using poly-l-lysine/poly(3,4-ethylenedioxythiophene)/porous graphene nanocomposite (PLL/PEDOT−PG) and poly(o-phenylenediamine)-imprinted film as a label-free and sensing platform. Fabrication of PEDOT−PG nanocomposites was achieved through a simple liquid–liquid interfacial polymerization. Subsequently, poly-l-lysine (PLL) functionalization was employed to enhance the dispersibility and stability of the prepared PEDOT−PG, as well as promote its adhesion on the sensor surface. In the presence of DBP, the imprinted poly(o-phenylenediamine) film was formed on the surface of PLL/PEDOT−PG. Investigation of the physical properties and electrochemical behavior of the MIP/PLL/PEDOT−PG indicates that the incorporation of PG into PEDOT, with PLL uniformly wrapping its surface, significantly enhanced conductivity, carrier mobility, stability, and provided a larger surface area for specific recognition sites. Under optimal experimental conditions, the electrochemical response exhibited a linear relationship with a logarithm of DBP concentration within the range of 1 fM to 5 µM, with the detection limit as low as 0.88 fM. The method demonstrated exceptional stability and repeatability and has been successfully applied to quantify DBP in plastic packaging materials.

“…PAEs are not chemically bonded with plastic polymers, but through hydrogen bonding and van der Waals force, so PAEs can easily migrate from plastic to the environment and then to the human body [2]. As PAEs are harmful to human development, metabolism, and the nervous system, the analysis of PAEs in biodegradable plastics is important for the protection of human physical health [3,4]. Many countries currently limit the highest residue levels of PAEs.…”

In this work, a novel electrospun nanofiber (PAN/TpBD; 2,4,6‐triformylphloroglucinol [Tp] and benzidine [BD]; polyacrylonitrile [PAN]) was fabricated via a facile electrospinning method and utilized as adsorbent in thin film microextraction (TFME) of phthalate esters (PAEs) (dimethyl phthalate, diethyl phthalate, diallyl phthalate, dibutyl phthalate, and dioctyl phthalate) in biodegradable plastics. The prepared PAN/TpBD combines the strong stability of nanofibers with increased exposure sites for covalent organic frameworks and enhanced interactions with the target, thus improving the enrichment effect on the target. The extraction efficiency of PAN/TpBD reached above 80%. Based on PAN/TpBD, a TFME‐high‐performance liquid chromatography method was established, and the experimental parameters were optimized. Under the optimal extraction conditions, the PAEs of this method varied linearly in the range of 10–10 000 µg/L with low detection limits (0.69–2.72 µg/L). The intra‐day and inter‐day relative standard deviation values of the PAEs were less than 8.04% and 8.73%, respectively. The adsorbent can achieve more than 80% recovery of the five targets after six times reuse. The developed method was successfully applied for the determination of trace PAEs in biodegradable plastics with recoveries ranging from 80.1% to 113.4% and relative standard deviations were less than 9.45%. The as‐synthesized PAN/TpBD adsorbent exhibited great potential in PAE analysis.
