General description

Gold nanoparticles (AuNPs) are colloidal nanoparticles with multiple surface functionalities that can be used in the development of new biomaterials. AuNP has a spherical structure with a large surface to volume ratio and excellent biocompatibility. It is majorly used in a variety of biomedical applications ranging from diagnostics to drug delivery.

Application

Ideal for adsorption of thiolated ligands such as oligonucleotides and polyethylene glycols. Also, due to the increased stability, these gold nanoparticles are ideal for use in physical and optical applications. Note: This product is not ideal for protein adsorption. For gold nanoparticles suitable for adsorption of proteins and other ligands for conjugate development, please see our gold nanoparticles stabilized in PBS.

This material is highly monodisperse (<12% variability in size and shape), and provides significantly improved surface reactivity. Applications include Surface Enhanced Raman Lables, Sensing/Detection, Biological Targeting, Plasmonics and Electronics.

Articles

Steven J. Oldenburg, Ph.D. provides an overview of lateral flow diagnostic assays and discusses the use of ultra-bright reporter particles based on the unique optical properties of gold nanoshells that significantly increase the sensitivity of lateral flow immunoassays.

Sustainable, environment-friendly, and clean energy sources with sufficiently high production efficiency for practical application are highly desirable to meet the energy challenge of the 21st century due to the world′s increasing energy demand.

Gold (Au) nanoparticles have tunable optical and electronic properties and are used in a number of applications including photovoltaics, sensors, drug delivery & catalysis.

Professor Ebrahimi and Professor Robinson (Pennsylvania State University, USA) summarize recent advances in the synthesis of these 2D materials, resulting material properties, and related applications in biosensing of neurotransmitters, metabolites, proteins, nucleic acids, bacterial cells, and heavy metals.
