Fluorescent Ti₃C₂MXene quantum dots for an alkaline phosphatase assay and embryonic stem cell identification based on the inner filter effect

Abstract

A Ti3C2QD-based fluorescent probe for an ALP activity assay and embryonic stem cell identification was developed by taking advantage of the inner filter effect.

MXene derivatives: synthesis and applications in energy convention and storage

“…40 The as-prepared MQDs showed the same hexagonal lattices as the MAX phase, while exhibited smaller diameters of less than 10 nm. 62 Generally, 0D MQDs are exfoliated from selected precursors via chemical or physical methods, such as hydrothermal/solvothermal, 63,64 ultrasound treatment 65,66 and reux. 46 Defects are created in this process and are served as the cutting points so that the layer sheets could be cut into smaller QDs.…”

Applications of fluorescent materials in the detection of alkaline phosphatase activity

“…The results showed LOD values as low as 0.3 mU L −1 , in addition to very good sensitivity. 15,89,90 Zheng et al…”

2D MXenes as Perspective Immobilization Platforms for Design of Electrochemical Nanobiosensors

“…A simple hydrothermal procedure (100 °C, 6 h, presence of NH 3 ) can produce quantum dots (QDs) with the size of (4.2±0.6) nm with subsequent application of QDs for fluorescent detection of alkaline phosphatase activity assay and for embryonic stem cell identification . Another hydrothermal method (150 °C, 5 h; ascorbate and Fe 3+ salt) was applied to prepare MXene modified by small magnetic particles with the size of 4.9 nm .…”

“…Thus, MXene dispersions are stable, what makes handling of MXene dispersions highly reproducible with subsequent robust and consistent patterning of surfaces. Besides application of MXenes in construction of electrochemical biosensors discussed here in details, there is a possibility to integrate MXenes into optical transducing platforms including surface plasmon resonance , total internal reflection imaging ellipsometry , fluorescence , fluorescence resonance energy transfer , electrogenerated chemiluminescence , and photoluminescence .…”
