Analysis of 10 nm Gold Nanoparticles using the Agilent 7800 ICP - MS
نویسنده
چکیده
High sensitivity and low background noise are critical for the detection of small nanoparticles by ICP-MS. The signal generated by the ionization of a nanoparticle decreases as the cube root of the diameter. This means detection of very small particles, such as 10 nm Au particles (NIST 8011), requires ICP-MS instrumentation with significantly higher sensitivity than is required for the more typical NIST reference materials such as NIST 8012 (30 nm) and 8013 (60 nm).

متن کاملBiodistribution of gold nanoparticles in mouse lung following intratracheal instillation
BACKGROUND The fate of gold nanoparticles, 2, 40 and 100 nm, administered intratracheally to adult female mice was examined. The nanoparticles were traced by autometallography (AMG) at both ultrastructural and light microscopic levels. Also, the gold content was quantified by inductively coupled plasma mass spectrometry (ICP-MS) and neutron activation analysis (NAA). The liver is the major site...

Nanoparticles (NPs) are defi ned as ultrafi ne particles with one dimension between 1–100 nm [1]. Because of their small size, they have a very large surface area relative to their weight, so they often react quite differently from a bulk solid or dissolved material of the same composition. For this reason they may offer novel and interesting properties for a broad range of applications. Curren...
متن کاملEvidence for biomagnification of gold nanoparticles within a terrestrial food chain.
Nanoparticles from the rapidly increasing number of consumer products that contain manufactured nanomaterials are being discharged into waste streams. Increasing evidence suggests that several classes of nanomaterials may accumulate in sludge derived from wastewater treatment and ultimately in soil following land application as biosolids. Little research has been conducted to evaluate the impac...
