Summary Some principles at the basis of the potential interest of macromolecular drugs are defined. The main lines of a research on purposely tailored synthetic high polymers acting as precursors of non-macromolecular active substances are given. The chemical aspects of proper design of these polymers are discussed in detail.

Characterization of Water-Soluble Macromolecular Substances in Cloud Water
Journal of Atmospheric Chemistry, 2004In this contribution we present to our knowledge the first investigations of macromolecular, often called humic-like substances (HULIS) in cloud water samples and compare them with water-soluble extracts from atmospheric PM2.5, soils and waters to study its possible origin.

Macromolecular changes of humic substances induced by interaction with organic acids
European Journal of Soil Science, 1996 Summary Two different humic materials, one from a forest soil and the other from wormcasts, were used to study the influence of mineral and organic acids on the conformational properties of humic substances. The macromolecular changes were followed by low pressure gel permeation chromatography after titrating ...

Deep eutectic solvent (DES) is a kind of solvent prepared by mixing hydrogen bond donors and hydrogen bond acceptors, and have become a hot topic in ecological civilization construction due to its low toxicity and sustainability. Its excellent properties such as low volatility, thermal stability and biodegradability make it stand out among many organic

AGGREGATION PATTERNS AND MACROMOLECULAR MORPHOLOGY OF HUMIC SUBSTANCES: A FRACTAL APPROACH
Soil Science, 1999Fractal geometry provides a powerful means for the quantitative description of heterogeneous and highly irregular systems encountered in nature. Humic substances represent a typical class of natural compounds that may be amenable to a fractal description because of their well known physical and chemical heterogeneity and molecular complexity.

MACROMOLECULAR STRUCTURES OF HUMIC SUBSTANCES
Soil Science, 1980ABSTRACTWe investigated humic substances by surface pressure and viscosity measurements at different pHs and neutral salt concentrations to elucidate their macromolecular configurations. We observed that such configurations were not unique; they varied with the changes in the medium.
