Stages and products of heparin thermolysis in the pristine state and adsorbed on the silica surface have been identified. SEM-images and the particle size distribution analysis showed that the modification of silica by heparin leads to deaggregation of silica particles, decrease of particles diameter and the narrower particle-size distribution. However, the main fraction of the particles remains in the form of aggregates with diameter between 50 and 500 nm.<\/em><\/p>\n<p><strong>\u00a0<\/strong><\/p>\n<p><strong>Key words: <\/strong>heparine, fumed silica, temperature programmed desorption mass spectrometry (TPD\u2011MS), photon correlation spectroscopy, scanning electron microscopy.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Physico-cmemical study of silica modified by heparine for developing of new drug release systems \u00a0 L.R.
