일반 설명

Gold nanoparticles (AuNPs) are quasi-dynamic materials which are commercially used for various biomedical, electrochemical and energy based applications.[1][2][3][4] AuNPs are highly stable with properties like high surface to volume ratio, high conductivity,[1] and low toxicity.[5]

애플리케이션

AuNPs can be potentially used in:
  • biomedical applications as a drug releasing agents[2]
  • cancer radiotherapy due to their excellent surface chemistry and biocompatibility[6][7]
  • electrochemical bio-sensing systems[3]

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.

  2. Hello,  I want to know if I can add CTAB (cétyltriméthylammonium bromide) to this solution and expect efficient adsorption with the AuNPs without interference with the already present stabilizer ? Thanks in advance 

    1 답변

    1. There have not been previous attempts on adsorption of non-thiolated ligands to the surfactant stabilized gold nanoparticles. It is difficult to say to what extent the surfactant may influence the adsorption of CTAB to the particles.

      Please test this by transferring 1 mL of gold nanoparticle suspension into a 1.5 mL centrifuge tube, centrifuge it at 17000 x g for 25-30 minutes, remove the supernatant, and resuspend the particles in a solution of water and CTAB (<1% v/v). If the sample appears to aggregate, then this will be a sign that the reagent is not compatible with the particles.

  5. What diluent should be used to dilute gold nanoparticle?

    1 답변

    1. This product is prepared as a susupension in a citrate buffer. It can be further diluted with water. Avoid diluting further with buffers containing other electrolyte salts such as sodium chloride. Due to the gold nanoparticle surface charge, aggregation and color changes will occur.
