magnetic-activated cell sorting macs provides a method for enriching a heterogeneous mixture of cells based upon extracellular properties, typically cell-surface proteins antigens .this is a column based separation technique where labeled cells are passed through a magnetic column. magnetic beads, called microbeads, are paired with a group .
electrostatic induction, also known as 'electrostatic influence' or simply 'influence' in europe and latin america, is a redistribution of electric charge in an object, caused by the influence of nearby charges. in the presence of a charged body, an insulated conductor develops a positive charge on one end and a negative charge on the other end.
gold extraction refers to the processes required to extract gold from its ores. . magnetic separation is also very effective for separating iron impurities. gold refining and parting. gold parting is primarily the removing of silver from gold and therefore increasing the purity of gold. .
polony sequencing is a development of the polony technology from the late 1990s and 2000s. methods were developed in 2003 to sequence in situ polonies using single-base extension which could achieved 5-6 bases reads. by 2005, these early attempts had been overhauled to develop the existing polony sequencing technology.
diamagnetism was first discovered when anton brugmans observed in 1778 that bismuth was repelled by magnetic fields. in 1845, michael faraday demonstrated that it was a property of matter and concluded that every material responded in either a diamagnetic or paramagnetic way to an applied magnetic field. on a suggestion by william whewell, faraday first referred to the phenomenon as .
