Source: Yong P. Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN Magnetic fields can be generated by moving charges, such as an electrical current. The magnetic field generated by a current can be calculated from the Maxwell equation. In addition, magnetic objects such as bar magnets can also generate magnetic fields due to microscopic dynamics of charges inside the material. Magnetic fields will exert magnetic force on other moving...

The uneven loss of medium from microtiter plates affects the reproducibility of uniform multicellular tumor spheroid formation. Improving culture conditions to reduce significant medium loss will improve the reproducibility of spheroid formation and the results of spheroid-based assays using the liquid-overlay technique.

Color in Coordination Complexes When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

The objective of this experiment is to achieve hands-on experience with different magnetic components from design and material perspectives. This experiment covers B-H curves of magnetic material and inductor design through identifying unknown design factors. The B-H curve of a magnetic element, such as an inductor or transformer, is a characteristic of the magnetic material forming the core around...
FAQs
Magnetic retention holds the beads, along with their bound targets, against the well surface or another collection area while liquid is removed. This positioning allows aspiration and buffer replacement without displacing the material being measured or purified. The mechanism is especially important when the assay depends on maintaining bead-associated antibodies, antigens, nucleic acids, or pathogen-related targets.
A controlled wash cycle removes and replaces liquid while the magnetic field keeps bead-bound material in place. This limits unintended transfer of residual liquid between stages and helps reduce carryover. More consistent removal of wash liquid can also lower background signal, which supports clearer results in bead-based antibody, antigen, nucleic-acid, and pathogen-detection assays.
Automation standardizes repeated separation, aspiration, buffer replacement, and liquid removal across multiwell plates. By reducing manual handling, it limits variation between wells and between processing runs. This consistency can improve reproducibility and analytical reliability, while the ability to process plates systematically supports higher throughput than workflows that depend entirely on individually handled washing steps.
A typical cycle first uses a magnetic field to immobilize the beads and their bound targets. Liquid is then aspirated, wash buffer is introduced, and the liquid is removed while the retained material remains positioned by the magnetic field. Repeating this sequence provides the washing step needed before subsequent assay or purification stages.
The instrument supports bead-based antibody and antigen assays, nucleic-acid purification, and pathogen-detection workflows. In immunology, it can help process assays that retain antibody- or antigen-associated material on magnetic beads. In infection research, the same washing principle can support nucleic-acid and pathogen-related workflows where controlled separation and reduced carryover are important.
Standardized washing can improve reproducibility, throughput, and analytical reliability across research and diagnostic settings. Consistent handling also reduces dependence on manual technique, making results more comparable across wells and processing runs. These benefits are relevant when many samples must undergo the same bead-based separation and washing sequence in immunology or infection studies.
