This study describes an imaging-based micro-neutralization assay to analyze the antigenic relationships between viruses. The protocol employs a flatbed scanner and has four steps, including titration, titration quantitation, neutralization, and neutralization quantitation. The assay works well with current circulating influenza A(H1N1)pdm09, A(H3N2), and B viruses.

Inductively Coupled Plasma-Mass Spectrometry (ICP-MS): Interferences
0 Views •
2024
Inductively coupled plasma–mass spectrometry (ICP–MS) is a highly selective and sensitive technique for accurate elemental analysis. Though the analysis of ICP–MS mass spectra is comparatively straightforward, it is affected by spectroscopic and non-spectroscopic interferences. Spectroscopic interferences arise when the plasma contains ionic species with an m/z value the same as the analyte ion. Spectroscopic interference can be categorized as isobaric, polyatomic ions, and refractory oxide ion...

Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview

2024
In inductively coupled plasma–mass spectrometry (ICP–MS), an inductively coupled plasma (ICP) torch is used as an atomizer and ionizer. Solid samples are dissolved and volatilized before being introduced into the high-temperature argon plasma, while solution samples are nebulized and passed through the high-temperature argon plasma. Plasma dissociates the analytes and ionizes their component atoms to form a mixture of positive ions and molecular species. The positive ions are then passed on to...

Optimal Foraging - Concepts

Optimal Foraging Organisms must acquire and use resources in their environment to survive. While food is one of the primary resources organisms must search for, individuals also need to seek habitats, shelter, and mates. This process of searching for resources is known as foraging, which involves a series of costs and benefits. More specifically, acquiring a resource provides the organism with a benefit, however, searching and capturing the resource requires expenditure of time and energy.
FAQs
Optimization treats sample preparation, plasma conditions, ion optics, mass filtering, and detector settings as an interconnected system. Changes at one stage can affect how efficiently analytes become ions, how those ions are transmitted, how mass-to-charge ratios are separated, and how signals are measured. Coordinating these stages helps balance sensitivity, accuracy, reproducibility, and interference control.
Sample preparation is important because the instrument must measure analytes within biological or materials-based samples, where matrix components can influence the result. Optimization therefore considers preparation alongside plasma and instrument settings rather than treating it as a separate task. Appropriate coordination helps reduce matrix-related effects and supports more reliable elemental measurements in complex samples.
Interference control depends on adjusting multiple parts of the measurement system. Plasma conditions affect ion formation, while ion optics influence ion transmission and mass filtering separates ions according to mass-to-charge ratio. Detector settings then affect signal measurement. Optimizing these elements together can minimize spectral and matrix interferences, improving detection limits and confidence in the reported concentrations.
A practical workflow considers the sample, plasma, ion path, mass separation, and detector in sequence while evaluating their combined effect on the measurement. Researchers adjust conditions to promote efficient ion formation, transmission, separation, and detection, then assess accuracy, sensitivity, reproducibility, and interference levels. This coordinated approach is more informative than changing a single setting without considering the full system.
In bioengineering, optimization is particularly useful when measuring trace metals in cells, biofluids, biomaterials, or tissue-engineered constructs. These samples may support different research questions, including assessment of nutrient and toxic metal levels or characterization of material composition. Optimized conditions help produce data suitable for comparing samples and evaluating elemental behavior in biological and engineered systems.
Optimized measurements can support trace-metal quantification with improved detection limits, data quality, and reproducibility. In bioengineering studies, the resulting information may help researchers assess nutrient or toxic metal levels, characterize elemental composition in biomaterials, and monitor metal uptake or release from tissue-engineered constructs. These outcomes strengthen interpretation of both biological responses and materials performance.
