Nanoparticle release is tested using a chamber system that includes a condensation particle counter, an optical particle counter and sampling ports to collect filter samples for microscopy analysis. The proposed chamber system can be effectively used for nanomaterial release testing with a repeatable and consistent data range.

A fundamental aspect of assessing the welfare of animals in captivity is to ask whether the animals have what they want. Here, we present a protocol to determine housing preference in the zebrafish (Danio rerio) with respect to the presence/absence of environmental enrichment and access to flowing of water.

This video describes the taste preference assay, a behavioral method used to measure attraction or avoidance towards colored solutions that taste differently by assessing the fly's abdominal coloration after ingestion of the preferred substance. The featured protocol demonstrates the procedure used to measure flies' preference towards solutions of varying sucrose concentrations.
FAQs
Time spent provides a broad measure of relative attraction or avoidance, whereas entries indicate how often the animal transitions between environments. Exploratory patterns add information about movement and engagement within the apparatus. Considering these measures together can distinguish a consistent chamber bias from behavior characterized by frequent switching or limited exploration.
Pairing a compartment with a social cue, object, odor, texture, or other condition gives the animal a specific environmental feature to evaluate. The resulting distribution of time and movement can indicate attraction, avoidance, or neutrality toward that feature. This design helps connect chamber preference with motivation, recognition, or sensory responsiveness.
The assay can reveal several behavioral processes depending on the paired conditions and measured responses. A preference may reflect motivation or reward-related attraction, while avoidance may be associated with anxiety-related responses or sensory sensitivity. When familiar and unfamiliar cues are used, chamber behavior can also provide evidence relevant to recognition and social behavior.
A basic procedure requires a two- or three-chamber apparatus, defined conditions assigned to compartments, and an animal allowed to move freely between them. Researchers maintain controlled testing conditions while recording time spent in each chamber, entries, and exploratory behavior. These measurements are then compared across the experimental environments to quantify the behavioral response.
These designs are useful when researchers need to compare an animal’s responses to distinct environments or stimuli within the same assay. Chambers can be associated with social cues, objects, odors, textures, or other experimental conditions. The flexible arrangement supports investigations of preference, avoidance, exploration, social behavior, sensory responses, and reward-related behavior.
In neurological or psychiatric disease models, chamber preference testing provides behavioral measures that may reflect altered motivation, recognition, anxiety-related avoidance, sensory processing, or social responses. Researchers can examine how an experimental condition changes time allocation, entries, or exploration across chambers. These outcomes connect observable behavior with broader disease-related changes in behavioral function.
