Analysis of Graphene quantum dots (GQDs) by UV-Vis Spectroscopy (CAT#: STEM-MB-0939-WXH)

Introduction

Graphene quantum dots (GQDs) are nanoparticles which show outstanding properties like exceptional biocompatibility, photostability, and cell membrane permeability owing to their small size and resistance to photobleaching over a long time.
Graphene quantum dots are studied as an advanced multifunctional material due to their unique optical, electronic, spin, and photoelectric properties induced by the quantum confinement effect and edge effect. They have possible applications in treatment of Alzheimer's disease, bioimaging, cancer therapeutics, temperature sensing, drug delivery, biosensors fabrication.

Principle

UV-Vis spectroscopy is an analytical technique that measures the amount of discrete wavelengths of UV or visible light that are absorbed by or transmitted through a sample in comparison to a reference or blank sample. This property is influenced by the sample composition, potentially providing information on what is in the sample and at what concentration. The only requirement is that the sample absorb in the UV-Vis region, i.e. be a chromophore. Absorption spectroscopy is complementary to fluorescence spectroscopy. Parameters of interest, besides the wavelength of measurement, are absorbance (A) or transmittance (%T) or reflectance (%R), and its change with time.

Applications

UV/Vis spectroscopy is routinely used in analytical chemistry for the quantitative determination of diverse analytes or sample, such as transition metal ions, highly conjugated organic compounds, and biological macromolecules. Spectroscopic analysis is commonly carried out in solutions but solids and gases may also be studied.
