Paper-Based Analytical Devices Based on Amino-MOFs (Mil-125, UiO-66 and Mil-101) as Platforms towards Biosensing Applications

Опубликована: Авг. 29, 2024

In this study, we have designed a promising platform based on metal-organic frameworks (MOFs) to develop paper-based analytical devices (PADs) immobilize biomolecules for application in biosensors. PADs become increasingly popular sensing applications recent years due their portability, low cost, simplicity, efficiency, fast detection capability, excellent sensitivity, and selectivity. addition, MOFs are an choice developing highly sensitive selective sensors. Their ability reversibly reproducibly adsorb desorb specific molecules allows using these materials as sensors various applications. They also offer the possibility modify structure properties, making them versatile adaptable different environments needs. research, synthesized characterized three amino-functionalized MOFs: UiO66-NH2 (Zr), MIL125-NH2 (Ti), MIL101-NH2 (Fe). These were used fabricate capable of portable monitoring alkaline phosphatase (ALP) enzyme activity by laser-induced fluorescence (LIF). Overall, amino-derivated MOF platforms demonstrate significant potential integration into biosensor PADs, offering key properties that enhance performance applicability chemistry diagnostics.

Recent Advances in Nanozyme Sensors Based on Metal–Organic Frameworks and Covalent–Organic Frameworks

Biosensors, Год журнала: 2024, Номер 14(11), С. 520 - 520

Опубликована: Окт. 23, 2024

Nanozymes are nanomaterials that exhibit enzyme-like catalytic activity, which have drawn increasing attention on account of their unique superiorities including very high robustness, low cost, and ease modification. Metal-organic frameworks (MOFs) covalent-organic (COFs) emerged as promising candidates for nanozymes due to abundant activity centers, inherent porosity, tunable chemical functionalities. In this review, we first compare the enzyme-mimicking centers mechanisms between MOF COF nanozymes, then summarize recent research designing modifying with activity. Moreover, typical examples sensing applications based these presented, well translation enzyme into a visible signal response. At last, discussion current challenges is followed by some future prospects provide guidance nanozyme sensors MOFs COFs practical applications.
