Current analyses show a widespread occurrence of microplastic particles in food products and raise the question of potential risks to human health. Plastic particles are widely considered to be inert due to their low chemical reactivity and therefore supposed to pose, if at all only minor hazards. However, variable physicochemical conditions during the passage of the gastrointestinal tract gain strong importance, as they may affect particle characteristics.

This contribution addresses two important issues in colloidal science: (i) differences and analogies between growth processes of different metals such as gold and silver and (ii) the influence of a steric stabilizing agent on the growth process. The results reveal that a growth due to coalescence is a fundamental growth principle if the monomer-supplying chemical reaction is faster than the actual particle formation.

- Recent efforts aim to enhance the efficiency of fluorescence immunoassays by using micro- or nanocrystalline dyes instead of traditional labeling molecules.
- The study explores the use of amphiphilic polymers as a simpler alternative to the complex layer-by-layer assembly method, which typically involves polyelectrolytes and biorecognition molecules like immunoglobulins.
- It evaluates how factors like surface charge and particle size affect the performance of these immunoassays, revealing important insights for improving their effectiveness.
