In Kinetic Interaction of Microparticles in Solution (KIMS), what happens when the drug sample increases?

In Kinetic Interaction of Microparticles in Solution (KIMS), the correct understanding is that as the drug sample increases, there is a notable impact on the absorbance readings. Generally, when the concentration of a substance, such as a drug, increases in a solution, it leads to an increase in the number of particles interacting with light. This heightened interaction usually results in a decrease in the light that is transmitted through the solution, consequently lowering the absorbance.

Absorbance is directly related to the concentration of the absorbing species in the solution; hence, with more drug present, more light is absorbed, which could initially seem counterintuitive in terms of decreasing absorbance. However, in this context, we might consider that a very high concentration could lead to phenomena such as saturation or increased scattering that could effectively reduce the measurable absorbance.

Understanding these interactions is critical in applications such as drug formulation and analysis, where monitoring changes in light absorbance can indicate concentration changes and help in assessing the effectiveness of a drug at varying levels. Thus, in KIMS, the increase in a drug sample results in decreased absorbance due to these interactions.
