distilling the horns and hoofs of oxen. They called this ammonia solution "spirits of hartshorn." Later, more substantial amounts of ammonia were recovered from the vapors of natural steam vents in Italy, and large quantities of ammonia were produced from Chile saltpeter (sodium nitrate, or NaNO3), which is mined in South American deserts. Around the turn of the twentieth century, Sir William Cro
membranes to facilitate drug delivery. At the same time, it is also required to retain the drug stability and ensure that early degradation of drugs from the nanocarriers does not take place.
Therefore, for drugs to be successfully delivered to their target, many factors such as its size, biocompatibility, target specific affinity, avoidance of reticuloendothelial systems, stability in blood,
