Gold Nanoparticle Uptake by Tomato Plants Characterized by Single Particle ICP-MS

27 Aug 2015

With the increasing use of engineered nanoparticles (ENPs) in a variety of products and processes, there is concern about the release of ENPs into and impact on the environment. One aspect of the environmental impact of ENPs that must be explored is their uptake by plants, as ENPs can make their way to plants via migration through water and/or soil. Research limitations can be avoided by careful choice of the ENP extraction procedure and performing the analysis with single particle ICP-MS (SP-ICP-MS), the combination of which will preserve the particle size information, allow for rapid analysis of a large number of samples, and yield results on the particle size, concentration, and size distribution. This application note explores such a technique for analysis of gold nanoparticle uptake in tomato plants.

NexION 350 ICP-MS Spectrometers

PerkinElmer

When your instrument is more efficient and productive, so too are your scientists and your lab. And nothing puts the flow in your workflow better than the NexION® 350 ICP-MS. With a data acquisition speed 10 times faster than any other ICP-MS on the market, the new NexION 350 ICP-MS opens up a whole new world of efficiency and opportunity, allowing you to measure more in less time, and accurately characterize nanoparticles. In addition to the exceptional application flexibility afforded by its speed, the instrument also delivers superior uptime and productivity through a variety of unique features engineered to enhance signal stability: Triple Cone Interface produces the industry’s most tightly focused ion beam and prevents sample deposition on internal components. Quadrupole Ion Deflector turns positively charged ions 90° into the Universal Cell and filters off neutrals. Analyzing Quadrupole made of a unique steel alloy for negligible thermal expansion for unparalleled stability. No extraction lenses to clean for minimized maintenance.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place.
