Decomposer, they eat dead organic material
A rapid lateral flow immunoassay is presented that uses carboxyl-modified superparamagnetic nanoparticles as labels that can be quantified by highly sensitive multi-channel electronic readers. The approach is generic in that it is likely to be applicable to numerous small molecules. The method permits both single- and multiplex assays at a point-of-need without sample pretreatment. It is user-friendly and offers attractive characteristics demonstrated here for detection of morphine, fentanyl and methamphetamine in . The competitive immunoassay uses commercially available reagents that do not require special permissions. After migration of sample, the lateral flow test strips are subjected to an alternating magnetic field at two frequencies. The response from the nanolabels is readout at a combinatorial frequency from the entire volume of a porous immunochromatographic membrane by the magnetic particle quantification technique.
application to the determination of drugs of abuse.
Estimating the detection time of a drug in urine is complex because of many different influencing factors and the lack of experimental data. Detection times vary depending on dose and route of administration, metabolism and characteristics of the screening and confirmation assays. Using a cut-off value of 1000 ng/mL, urinary samples can be positive for amphetamine for up to 5 days after intake of the drug.

Fibrin is an insoluble component of plasma that forms a meshwork of strands and is considered the structural basis of clot formation.
<h3>What is clot formation?</h3>
- Blood turns from a liquid to a gel during coagulation, which results in the formation of blood clots.
- Possible outcomes include haemostasis, which stops blood loss from a broken vessel, followed by repair.
- The activation, adhesion, and aggregation of platelets, as well as the deposition and maturation of fibrin, are all components of the coagulation process.
<h3>What is fibrin?</h3>
- A fibrous, non-globular protein called fibrin is necessary for blood to clot.
- It is created when fibrinogen undergoes polymerization due to the protease thrombin.
- A haemostatic plug or clot is formed over a wound site by platelets and polymerized fibrin.

I think it would be c. 1.5 because it is half the size. Also good luck for your quiz
