Abstract: This invention provides methods for producing a polymer particle which contains unusually high negative charges on the surface of the particle. Preferably, the polymer is pharmaceutically acceptable. The negative charges can be conferred by chemical groups such as carboxyl, sulfonate, nitrate, fluorate, chloride, iodide, persulfate, and many others, with carboxyl group being preferred. The invention also provides polymer particle produced by the methods of the invention.
