Cu- and Sn-Codoped Mesoporous BaTiO3-G-SiO2 Nanocomposite for Bioreceptor-Free, Sensitive, and Quick Electrochemical Sensing of Rhizopus stolonifer Fungus

“…To resolve sensor development challenges, researchers have produced modified chemical electrodes that use polymers (e.g., polyaniline and polypyrrole) and quaternary nanocomposites. − With its high refractive index and low loss, BaTiO 3 has recently been proven to offer substantial shifts in resonance angle with tiny refractive index changes . Also, BaTiO 3 , which has good sensing capacity, has also been used for water samples with acceptable recovery values that turned into harmful contaminants .…”

Advanced polymeric/inorganic nanohybrids: An integrated platform for gas sensing applications

“…Oh and colleagues studied the H 2 S gas sensing properties of novel nanohybrid sensors based on quaternary semiconductor (BaInSbSe 5 ), graphene and polypyrrole (Oh et al, 2021c). In contrary to the traditional sensors based on polypyrrole, this study simplifies the operation of sensors for real sample analysis due to the presence of semiconductor.…”

“…The excellent sensing performance of the sensors was associated to the high adsorption capacity and low band energy gap. Therefore, the fabricated sensor is a potential candidate for environmental and industrial applications due to its highly stable sensitivity and selectivity along with the outstanding repeatability (Oh et al, 2021c). Sensing performance of different polymeric/inorganic nanohybrids for detection of hydrogen sulphide has been given in Table 4.…”

“…For sensing of hydrogen, PANI based nanohybrids (i.e., PANI-SnO 2 -Pd and PANI-Sm 2 O 3 ) also showed high response and great sensitivity (Pippara et al, 2021). Polymeric nanohybrids based on PPy showed high sensing potential for the H 2 S (900-1400%) (Oh et al, 2021c), CO 2 (720%) (Kumar et al, 2020), NO 2 (4500%) (J. Zhang et al, 2020a) and LPG (116%) gases.…”

A flexible mesoporous Cu doped FeSn–G–SiO2composite based biosensor for microalbumin detection

“…Biomolecules are also effectively captured by this surface-to-volume ratio and the improved stacking contact between hexagonal structures and carbon-based ring structures. [10][11][12][13] Research on the absorbability of biosensors using graphene is prevalent. [14][15][16][17] In addition, Cudoping in nanoparticles is widely regarded as an effective method to enhance device performance by increasing electrical conductivity.…”
