  Bioactive agents may be reproducibly converted into particles having diameters in the range of about 5 to about 2000 nanometers (nm). Conversion is accomplished by dissolving the bioactive agent in a solvent for the bioactive agent, and rapidly altering the polarity of the solution to make it a non-solvent for the bioactive agent, for example by diluting the bioactive agent solution with an excess of a liquid that is a non-solvent for the bioactive agent but is miscible with the solvent. Precipitated bioactive agent nanoparticles are collected by centrifugation, filtration or lyophilization. The nanoparticles have a relatively narrow size distribution, and the average diameter can be controlled by choice of solvent and non-solvent. The nanoparticles are typically amorphous. A surfactant may be added to ensure dispersion of the particles when administered. In the preferred embodiment, the bioactive agent is a drug with low aqueous solubility.

  生物活性物质可以被稳定地转化成直径在约5到2000纳米（nm）范围内的颗粒。转化是通过将生物活性物质溶解在其溶剂中，并迅速改变溶液的极性使其成为生物活性物质的非溶剂来完成的，例如通过将生物活性物质溶液与过量的非溶剂液体混合来稀释生物活性物质溶液。通过离心、过滤或冻干收集沉淀的生物活性物质纳米粒子。纳米粒子具有相对较窄的尺寸分布，平均直径可通过选择溶剂和非溶剂来控制。纳米粒子通常是无定形的。可以添加表面活性剂以确保在给药时颗粒的分散。在首选实施例中，生物活性物质是一种具有低水溶性的药物。

  Delivery of bioactive molecules such as nucleic acid molecules encoding a protein can be significantly enhanced by immobilization of the bioactive molecule in a polymeric material adjacent to the cells where delivery is desired, where the bioactive molecule is encapsulated in a vehicle such as liposomes which facilitates transfer of the bioactive molecules into the targeted tissue. Targeting of the bioactive molecules can also be achieved by selection of an encapsulating medium of an appropriate size whereby the medium serves to deliver the molecules to a particular target. For example, encapsulation of nucleic acid molecules or biologically active proteins within biodegradable, biocompatible polymeric microparticles which are appropriately sized to infiltrate, but remain trapped within, the capillary beds and alveoli of the lungs can be used for targeted delivery to these regions of the body following administration to a patient by infusion or injection.

  将生物活性分子（如编码蛋白质的核酸分子）固定在需要递送的细胞附近的聚合物材料中，可以大大提高生物活性分子（如编码蛋白质的核酸分子）的递送效果，其中生物活性分子被包裹在脂质体等载体中，有利于将生物活性分子转移到目标组织中。生物活性分子的靶向性还可以通过选择适当大小的封装介质来实现，介质的作用是将分子输送到特定的靶点。例如，将核酸分子或生物活性蛋白质封装在可生物降解、生物相容性好的聚合物微粒中，这种微粒大小适当，可渗入肺部的毛细血管床和肺泡，但仍被困在其中，通过输液或注射给病人用药后，可将核酸分子或生物活性蛋白质定向输送到身体的这些区域。

  Bioadhesive polymers in the form of, or as a coating on, microcapsules containing drugs or bioactive substances which may serve for therapeutic, or diagnostic purposes in diseases of the gastrointestinal tract, are described. The polymeric microspheres all have a bioadhesive force of at least 11 mN/cm2 (110 N/m2). Techniques for the fabrication of bioadhesive microspheres, as well as a method for measuring bioadhesive forces between microspheres and selected segments of the gastrointestinal tract in vitro are also described. The quantitative method provides a means to establish a correlation between the chemical nature, the surface morphology and the dimensions of drug-loaded microspheres on one hand and bioadhesive forces on the other, allowing the screening of the most promising materials from a relatively large group of natural and synthetic polymers which, from theoretical consideration, should be used for making bioadhesive microspheres.
