Here, we present a protocol to quantify allergen-loaded particles by flow cytometry. Ambient particulate matter particles may act as carriers of adsorbed allergens. We show here that flow cytometry, a method widely used to characterize suspended solids >0.5 µm in diameter, can be used to measure these allergen-loaded particles.

Determining the fungal diversity within an environment is a method utilized in occupational health studies to identify health hazards. This protocol describes DNA extraction from occupational air samples for amplification and sequencing of fungal ITS regions. This approach detects many fungal species that can be overlooked by traditional assessment methods.
FAQs
Resistance develops as adjacent layers transfer momentum through molecular collisions and cohesive forces. When one layer moves relative to another, these interactions oppose the difference in motion, so maintaining a particular shear rate requires applied force. This molecular-scale momentum transfer explains why internal friction influences how readily a chemical liquid moves through a system.
A more viscous fluid offers stronger resistance to relative motion between its layers. Consequently, increasing the force is necessary to sustain the same rate of shearing rather than allowing motion to slow. This relationship matters when evaluating flow behavior, because viscosity links the mechanical effort applied to the resulting movement within the fluid.
Higher viscosity slows the movement of suspended particles and dissolved species through the liquid. The increased resistance limits how quickly these components can move relative to the surrounding fluid, which can influence mixing and transport. Chemists therefore consider viscosity when predicting how uniformly materials move through formulations or other liquid systems.
At comparable flow conditions, a higher-viscosity fluid needs more force to maintain motion and generally moves more slowly than a lower-viscosity fluid. This distinction helps explain why liquids behave differently during flow, mixing, coating, and transport. The comparison is based on resistance to layer motion rather than on the fluid's composition alone.
Viscosity measurements help characterize liquids and monitor their composition. They also provide information for predicting how a material will behave during processing and transport. Because the measured resistance reflects molecular interactions within the liquid, changes in viscosity can serve as a practical indicator that the liquid's characteristics or composition have changed.
Chemists should account for it when designing mixing processes, flow systems, coatings, or formulations. The relevant considerations include the force needed to maintain motion and the slower movement of suspended or dissolved components in more viscous liquids. Including these effects helps predict processing behavior and how materials will move during transport.
