“…However, further developments and applications of quantum dots (QDs) in general, require the implementation of simple "routine" synthesis methods to ensure run-to-run reproducibility, automation possibilities, and standardization of the nanomaterials. [1] In this context, the high temperatures required for these synthesis are a major drawback, [10,11] which, beyond obvious energetic concerns, imposes in addition the use of high-boiling-point solvents. Then, strenuous purification procedures are required and residual solvent cannot be totally removed, resulting in high carbon contents.…”

“…Colloidal luminescent semiconductor nanocrystals, or QDs, have a range of potential applications, including optoelectronics (lighting and advanced displays), optics (lasers), solar energy, biotechnology, and medicine [509]. However, since their inception as biological labels, applications in the biological arena have developed exponentially [283,[510][511][512][513][514][515].…”

FRET – Förster Resonance Energy Transfer

View full text Add to dashboard Cite

The intrinsic sensitivity (r 6 dependence) of F€ orster (or fluorescence) resonance energy transfer (FRET) to nanoscale changes in the donor/acceptor separation distance has made FRET an invaluable biophysical tool in a variety of applications, ranging from studying the structure and conformation of proteins and nucleic acids to examining biomolecular interactions, including its use in in vitro and in vivo bioassays [1][2][3][4][5][6][7]. While the myriad of FRET configurations and techniques currently in use are covered throughout this book, here we focus primarily on the materials utilized as donor or acceptor probes in FRET rather than the process itself [3,5,8,9]. Our 2006 review paper on this topic serves as the foundation for this updated chapter [3]. The materials were divided into three main categories: organic materials that include "traditional" dye fluorophores, dark quenchers, polymers, and carbon nanomaterials (NMs); inorganic materials such as metal chelates, metal, and semiconductor nanocrystals; and fluorophores of biological origin such as fluorescent proteins (FPs), amino acids, and fluorescence generated from enzymatic bioluminescence (BL) and chemiluminescence (CL). These materials may function as FRET donors and/or acceptors, depending upon experimental design. Many of the new materials developed and/or new donor-acceptor probe combinations used address some of the inherent complications of more traditional FRET materials, including photobleaching, spectral cross talk, and direct excitation of the acceptor species, and examples of these will be highlighted and discussed throughout the chapter. Since the vast majority of FRET applications are biological in nature, they routinely involve some type of biomolecule labeling strategy, which ultimately plays a significant and fundamental role in the success and interpretation of the resulting FRET. Therefore, we begin the chapter with a brief discussion of the bioconjugation techniques commonly utilized for FRET and points to consider, followed by sections highlighting the current and emerging materials that are used, or have the potential to be used, in FRET applications.

“…They have been widely used in bio-imaging applications for a number of years, and researchers have recently developed methods to stop the fluorescence from quantum dots switching on and off in a random manner (a problem known as 'blinking') 9 . More recently the optical properties of colloidal quantum dots have been exploited in lighting to improve energy efficiency and make the output of light-emitting diodes seem more natural 10 , and applications in digital cameras, displays and solar power are also being investigated 10,11 . A challenge facing all companies building products with colloidal quantum dots is to move away from toxic materials such as cadmium.…”
