Graphene Quantum Dots
This document provides an introduction to graphene quantum dots. It discusses the fabrication of graphene through mechanical exfoliation, chemical vapor deposition, thermal decomposition of silicon carbide, and reduction of graphite oxide. It then covers the electronic band structure of graphene using a tight-binding model and effective mass approximation, highlighting properties like Dirac fermions and Berry's phase. Finally, it discusses the fabrication of graphene nanostructures and quantum dots, the role of edges, and effects of size quantization. The document serves as a preface and overview for a book on graphene quantum dots.

Gold nanoparticles are useful as biosensors due to their optical properties, ease of synthesis, stability, and ability to conjugate with biomolecules. The document describes how gold nanoparticles can be used to detect various analytes through colorimetric assays and lateral flow tests. It also discusses using quantum dots as novel biosensors and how their size-dependent optical properties allow tuning of fluorescence. Conditions are adjusted for new gold nanoparticle-based lateral flow tests to detect DNA methylation and SRY gene sequences.PowerPoint Slides from NanoMarkets Report on Quantum Dots

Quantum dots - A potential elixir in the field of biology
This document discusses quantum dots, which are nanoscale semiconductor crystals with size-dependent optical and electronic properties. It covers their properties like tunable light emission, photostability, and ability to be functionalized. Methods of fabricating quantum dots are described, including colloidal synthesis and growth on substrates. Applications discussed include biological imaging, drug delivery, and sensing. Both advantages like brightness and disadvantages like potential toxicity are mentioned.
Nanotechnology: Quantum Dots
QD have such remarkable properties that scientists think they will soon be used in everything from light bulbs to the design of ultra-efficient solar cells.
Quantum dots ppt
Quantum dots are semiconductor nanoparticles that confine electrons and holes in all three dimensions. They are made using different methods like lithography, colloidal synthesis, or epitaxy. Quantum dots have discrete energy levels that depend on their size and shape. They have potential applications in solar cells, LEDs, bioimaging, drug delivery, and anti-counterfeiting due to their tunable light emission properties.
