Abstract

Biomaterials are composed of biological particles, which are aggregated particle systems with complex spatial and fractal structures formed by smaller unit particles due to electrostatic forces, collisions, and adhesion. In this paper, the optical properties of aggregated particles were calculated based on optimized Ballistic Cluster-Cluster Aggregation (BCCA) model. The effect of different porosity and monomer numbers of aggregates on the absorption and scattering properties is investigated. The properties were found to be enhanced with decreasing porosity and increasing number of particle monomers. And it is also found that the error due to the randomness of the structure of the aggregated particles under the same conditions enables the above conclusion to be completely satisfied when the particle number difference is greater than or equal to 6.
