Rapid lateral flow assays based on the quantification of magnetic nanoparticle labels for multiplexed immunodetection of small m
PolarNik [594]

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.

Which of the following are common traits of chloroplasts and mitochondria?
Delvig [45]

Answer:

c. Both have their own DNA.

Explanation:

Both chloroplast and mitochondria are semi-autonomous organelles which means that they both have their own DNA. Both of these organelles have a circular DNA and make some of their own proteins by themselves. Both are double membrane-bound organelles. Chloroplast has a third membrane system called thylakoid.

Chloroplasts are found in the plant cells only as they are the site for photosynthesis. Mitochondria are present in both plant and animal cells and are the site for cellular respiration to produce energy to support the vital functions of cells.

Why do you have to determine the total magnification when observing a specimen under the compound microscope?
IceJOKER [234]

Answer:

To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.

Explanation:

A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.
