Key Differences
Multimolecular Colloids consist of aggregates or clusters of smaller molecules or particles that come together to form a size range typical of colloids. On the contrary, Macromolecular Colloids have their colloidal size due to the inherent large size of individual molecules.
In the realm of colloidal science, Multimolecular Colloids often result from the accumulation of atoms or small molecules. Gold sol is an example where tiny gold particles aggregate to form this type of colloid. Meanwhile, Macromolecular Colloids arise from single, giant molecules like polymers or proteins dispersing in a solvent.
One of the key differences between Multimolecular Colloids and Macromolecular Colloids lies in their formation. While the former results from external forces or conditions making small particles come together, the latter involves the dispersion of naturally large molecules in a medium.
Understanding the behavior of Multimolecular Colloids often requires studying how individual particles interact and aggregate under various conditions. On the other hand, studying Macromolecular Colloids usually delves into how large molecules like proteins or polymers interact with solvents or other molecules.
In applications, Multimolecular Colloids might be used where the properties of aggregated particles are beneficial, such as in certain catalysts. In contrast, Macromolecular Colloids, due to their large molecular size, are prevalent in areas like polymer science and biochemistry.
