Metal organic frameworks (MOFs)-based fluorescent CA125 analysis: A comparative study of the quenching effects of MIL-101, Cu-MOF, ZIF-8, UiO-66
Metal-organic frameworks (MOFs) are a class of materials with highly ordered pore structures. Due to their unique physical and chemical properties, they show great potential in the field of biosensors. Some MOFs can adsorb fluorescently labeled nucleic acid aptamers through various interaction mechanisms (such as electrostatic interactions, π-π stacking, hydrogen bonding, etc.). These interactions not only ensure the stable binding of the aptamers but also allow for their controlled release under specific conditions (such as changes in pH, temperature, or the presence of specific molecules). This mechanism provides multiple possibilities for the design of biosensors. Herein, we have systematically compared the quenching effects of widely used MOFs that can bind to aptamers, i.e., Fe-MOF (MIL-101), Cu-MOF, Zn-MOF (ZIF-8) and Zr-MOF (UiO-66). The study on the kinetics, quenching efficiency, and influencing factors such as ionic strength pH and temperature is performed. Interestingly, Cu-MOF exhibits superior quenching abilities to the other three materials in both the quenching efficiency and kinetics. Thus, a Cu-MOF based fluorescent sensor is reported to detect the ovarian cancer marker carbohydrate antigen 125 (CA125), which provides convenient detection performance (assay time about 10 min), and a detection range from 0.1 to 400 ng/mL. Moreover, it is designed in a simple mix-and-detect format and can be directly applied to clinical sample detection. This work may offer guidance for the choice of MOFs and elaborate design of biosensors.
期刊介绍:
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
