“…Since the beginning of this century, the gas sensing of some polyaniline hybrid materials has been reported. These hybrid materials include NO 2 and triethylamine with SnO 2 -ZnO/PANI [ 6 , 7 ], H 2 S, CO, NH 3 , and volatile organic compounds with PANI/SnO 2 [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ], E. coli bacteria, acetone, ammonia, ethanol, and CO with PANI/TiO 2 [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 ], and NH 3 with PANI/MoO 3 and PANI/nano-In 2 O 3 [ 25 , 26 , 27 , 28 ]. Recently, numerous studies have been reported on the benzene gas sensing behavior of these hybrids such as polyaniline/graphene [ 29 , 30 ]; however, reports on the detection of benzene gases at low concentrations are limited.…”

A sensor operating at room temperature has low power consumption and is beneficial for the detection of environmental pollutants such as ammonia and benzene vapor. In this study, polyaniline (PANI) is made from aniline under acidic conditions by chemical oxidative polymerization and doped with tin dioxide (SnO2) at a specific percentage. The PANI/SnO2 hybrid material obtained is then ground at room temperature. The results of scanning electron microscopy show that the prepared powder comprises nanoscale particles and has good dispersibility, which is conducive to gas adsorption. The thermal decomposition temperature of the powder and its stability are measured using a differential thermo gravimetric analyzer. At 20 °C, the ammonia gas and benzene vapor gas sensing of the PANI/SnO2 hybrid material was tested at concentrations of between 1 and 7 ppm of ammonia and between 0.4 and 90 ppm of benzene vapor. The tests show that the response sensitivities to ammonia and benzene vapor are essentially linear. The sensing mechanisms of the PANI/SnO2 hybrid material to ammonia and benzene vapors were analyzed. The results demonstrate that doped SnO2 significantly affects the sensitivity, response time, and recovery time of the PANI material.

“…The signals that are specific to a particular area appear at a lower wavelength than those in PANI. This is due to the co-polymers being less conjugated [ 54 ] when compared to PANI. The λ max of this wavelength band depends on the co-polymer oxidation and the carboxylate group’s steric hindrance can affect the co-planarity of the π system.…”

“…Most of them formed globular compact structures that indicated the crystalline structure of the sample. Additionally, the grains of the nanoparticles were found to be interconnected with each other, which indicates that they have enough binding energy to combine with neighboring grains or molecules [ 54 ]. Pure PANI obtained via the chemical oxidation route is shown in Figure 5 c, whereby we see that the particles have spherical agglomeration without uniform packing [ 76 ].…”

Breast cancer (BC) is one of the most common types of cancer disease worldwide and it accounts for thousands of deaths annually. Lapatinib is among the preferred drugs for the treatment of breast cancer. Possible drug toxicity effects of lapatinib can be controlled by real-time determination of the appropriate dose for a patient at the point of care. In this study, a novel highly sensitive polymeric nanobiosensor for lapatinib is presented. A composite of poly(anilino-co-4-aminobenzoic acid) co-polymer {poly(ANI-co-4-ABA)} and coffee extract-based green-synthesized indium nanoparticles (InNPs) was used to develop the sensor platform on a screen-printed carbon electrode (SPCE), i.e., SPCE||poly(ANI-co-4-ABA-InNPs). Cytochrome P450-3A4 (CYP3A4) enzyme and polyethylene glycol (PEG) were incorporated on the modified platform to produce the SPCE||poly(ANI-co-4-ABA-InNPs)|CYP3A4|PEG lapatinib nanobiosensor. Experiments for the determination of the electrochemical response characteristics of the nanobiosensor were performed with cyclic voltammetry (CV) and differential pulse voltammetry (DPV). The nanobiosensor calibration for 0–100 ng/mL lapatinib was linear and gave limit of detection (LOD) values of 13.21 ng/mL lapatinib and 18.6 ng/mL lapatinib in physiological buffer and human serum, respectively. The LOD values are much lower than the peak plasma concentration (Cmax) of lapatinib (2.43 µg/mL), which is attained 4 h after the administration of a daily dose of 1250 mg lapatinib. The electrochemical nanobiosensor also exhibited excellent anti-interference performance and stability.

A spontaneous polarization that occurs below the Curie temperature is characteristic for ferroelectric materials. This polarization is sensitive to many external conditions such as an electric field, mechanical deformation, temperature, and chemical and biological factors. Therefore, bulk ferroelectric materials have been used for decades in sensors and actuators. Recently, special attention has been paid to ferroelectric nanostructures that represent better sensing properties than their bulk counterparts. This paper presents a comprehensive survey of applications of nanoferroelectrics in different types of sensors, e.g., gas sensors and piezoelectric, pyroelectric, and piezoresistive sensors of mechanothermal signals, as well as photodetectors, ionizing radiation detectors, and biosensors. The recent achievements and challenges in these fields are summarized. This review also outlines the prospects for future development of sensors based on nanosized ferroelectrics.
