Summary
Graphene oxide surfaces can be used to monitor mesenchymal stem cell differentiation. A new fluorescence spectroscopy method allows in-situ detection of osteogenic induction on opaque materials.
Area of Science:
- Biomaterials Science
- Stem Cell Biology
- Materials Chemistry
Background:
- Graphene and graphene oxide promote mesenchymal stem cell (MSC) adhesion, growth, and differentiation.
- Graphene coatings accelerate human MSC osteogenic differentiation.
- Conventional Alizarin Red S (ARS) staining quantifies osteogenic induction by detecting calcium deposits.
Purpose of the Study:
- To develop a method for in-situ detection and monitoring of osteogenic differentiation on opaque graphene oxide surfaces.
- To overcome limitations of conventional ARS staining on non-transparent materials.
Main Methods:
- Utilizing the 2D-fluorescence spectra of the Alizarin Red S-calcium complex.
- Developing a novel detection and monitoring technique for in-situ osteogenic induction.
- Applying the method to opaque graphene oxide materials.
Main Results:

01:062D NMR: Homonuclear Correlation Spectroscopy (COSY)
2.0K
Homonuclear correlation spectroscopy, or COSY, is a 2-dimensional NMR technique that provides information about coupled protons. Typically, the geminal and vicinal coupling are observed. For example, consider the COSY spectrum of ethyl acetate, where its 1D proton NMR spectrum is plotted along the vertical and horizontal axes with their corresponding chemical shift scale. Three spots on the diagonal corresponding to the three peaks in the 1D proton spectrum are called diagonal peaks. The COSY...

Atomic fluorescence spectroscopy (AFS) is an analytical technique that involves the electronic transitions of atoms in a flame, furnace, or plasma being excited by electromagnetic (EM) radiation. When these atoms absorb energy, they become excited and subsequently release energy as they return to their original state. This emitted light, or "fluorescence," is observed at a right angle to the incident beam. Both absorption and emission processes transpire at distinct wavelengths, which...

01:192D NMR: Heteronuclear Single-Quantum Correlation Spectroscopy (HSQC)
1.4K
Heteronuclear single-quantum correlation spectroscopy (HSQC) is a 2D NMR technique that reveals one-bond correlations between hydrogen and a heteronucleus. The HSQC experiment is similar to the heteronuclear correlation experiment (HETCOR) but is more sensitive. In the HSQC spectrum, the proton chemical shift is plotted on the horizontal F2 axis, while the 13C chemical shift is plotted on the vertical F1 axis. The corresponding proton and 13C spectra are also shown. The HSQC contour plot does...

24.4K
Fluorescence in situ hybridization, or FISH, was developed in the early 1980s and has quickly become one of the most widely used techniques in cytogenetics. Labeled probes are used to bind complementary DNA or RNA sequences on a chromosome or in a region within a cell. Earlier, the probes could only be obtained by cloning or reverse transcription of a DNA template. Currently, the probe oligonucleotides can be synthesized synthetically. Additionally, with the advancement of optical techniques,...

In redox reactions, the transfer of electrons occurs between reacting species. Electron transfer is described by a hypothetical number called the oxidation number (or oxidation state). It represents the effective charge of an atom or element, which is assigned using a set of rules.

2.8K
Atomic spectroscopy is a vital tool in elemental analysis, both qualitatively and quantitatively. It can be broadly divided into optical spectroscopy, mass spectroscopy, and X-ray spectroscopy methods. The optical spectroscopic methods are atomic absorption spectroscopy (AAS), atomic emission spectroscopy (AES), and atomic fluorescence spectroscopy (AFS). The first step in all three methods is atomization, where the solid, liquid, or solution-phase samples are converted into gas-phase atoms and...
