Nanomicro Tech provides a series of Magnetic Particles with narrow size distribution and super-paramagnetism. These small magnetic particles have a resin core and an iron oxide layer sandwiched between the core and an outermost layer. The outermost layer of the particles is inorganic SiO2 or a functionalized polymer which completely covers iron oxide to prevent it from potentially incompatible interaction with biomaterials. These magnetic particles have a very good dispersity with well controlled particle size and narrow particle size distribution.

The best time to end moulting
Moulting chickens, time before and after the uneven, early repairs moulting earlier; late feathering layers of thin layers of egg shells, egg weight reduction, fertility rate and hatching rate also decreased. Since chickens spend private conversations during this period, raising the cost of raising livestock, many people use the methods of feeding restrictions, limiting water, and limiting light to artificially force moulting. To take this approach, the first is to destroy the physical foundation of the chicken; the second is to take a long time, the laying hens can recover eggs in about 50 days. The second moult is concentrated in the chicken's life: for the first time, 42 days, the brooding feathers are transferred to the bred feathers, and the neck villi are faded. The second time, 126 days, the bred feathers were transferred to the laying hens. If moulting occurs during laying, it may be associated with seasonal, brooding, feed nutrition (especially animal protein, sulfur-containing amino acids: methionine, lack of cystine), parasites, obscurity, intestinal digestion and malabsorption etc. After the period due to the decline in the level of estrogen in the body can also cause moult.
