Hollow ZnS–CdS nanocage based photoelectrochemical sensor combined with molecularly imprinting technology for sensitive detection of oxytetracycline

A novel QCM immunosensor development based on gold nanoparticles functionalized sulfur-doped graphene quantum dot and h-ZnS-CdS NC for Interleukin-6 detection

“…The absorption band of h-ZnS-CdS NC material shifted to more positive (about 500 nm) in comparison with h-ZnS NC (about 350 nm). This positive absorbance shift was corresponded to CdS incorporation into h-ZnS NC [26].…”

“…After that, ZIF-8 RDs (100.0 mg) was transferred into methanol solution containing TA (2.0 g) under stirring treatment for 10 min. After yolk-shelled ZIF-8 RDs was washed with methanol (50.0 mL), the product was collected via centrifugation at 10,000 rpm [26]. After TAE (1.00 g) solution preparation in ethanol (100.0 mL), this solution was mixed with yolk-shelled ZIF-8 RDs (100.0 mg).…”

MOF@COF Heterostructure Hybrid for Dual-Mode Photoelectrochemical–Electrochemical HIV-1 DNA Sensing

“…54,55 A Co-MOF@TPN-COF nanoarchitecture has been developed and exploited as novel platforms for an oxytetracycline aptasensor, giving an extremely low LOD of 0.217 fg mL −1 detected by the electrochemical technique, 54,55 much lower than the biosensors for detecting oxytetracycline using other nanomaterials as platforms. 56,57 Thus far, however, there is no report on the construction of the dual-mode PEC−EC biosensors for the detection of HIV-1 based on the core−shell MOF@COF hybrids with π−π stacking interaction and sizable specific surface.…”

“…The MOF@COF hybrids can effectively integrate unique advantages of their parents, producing novel porous nanomaterials with outperformed physicochemical properties. , By integrating the aromaticity of MOFs and the ordered pillar–columnar structure characteristics of COFs, the fabricated MOF@COF hybrid materials display a strong π–π stacking interaction, overcoming the inherent disadvantages of sole MOFs and COFs and resulting in a synergistic effect to provide multifunctional properties for specific and personalized applications. Diverse MOF@COF heterostructures have been developed and used as catalysts, − gas adsorbents, supercapacitors, and biosensors. , A Co-MOF@TPN-COF nanoarchitecture has been developed and exploited as novel platforms for an oxytetracycline aptasensor, giving an extremely low LOD of 0.217 fg mL –1 detected by the electrochemical technique, , much lower than the biosensors for detecting oxytetracycline using other nanomaterials as platforms. , Thus far, however, there is no report on the construction of the dual-mode PEC–EC biosensors for the detection of HIV-1 based on the core–shell MOF@COF hybrids with π–π stacking interaction and sizable specific surface.…”

Cobalt-Iron Double Ion-Bovine Serum Albumin Chelation-Assisted Thermo-Sensitive Surface-Imprinted Nanocage with High Specificity

“…As a new adsorbent, MIPs possessed the advantages of high mechanical stability, good physical and chemical stability, strong selectivity, low cost, and easy preparation. They have been widely used in chemical sensors, − chemical analysis and detection, − chromatographic separation, − and other fields. At present, MIPs are mostly used in the adsorption and separation of various kinds of heavy metals, organics, and sulfur pollutants and other small molecules. − The research is becoming mature.…”
