Source: Laboratories of Dr. Ian Pepper and Dr. Charles Gerba - The University of Arizona Demonstrating Author: Bradley Schmitz Fungi are heterotrophic eukaryotic organisms, and with the exception of yeasts, are aerobic. They are abundant in surface soils and are important for their role in nutrient cycling and the decomposition of organic matter and organic contaminants. White rot fungi (phanerochaete chryosporium) for example, (Figure 1) are known to degrade aromatics. Figure 1. White rot on...

FAQs
Curing crosslinks the polymer chains in uncured PDMS, converting a flowable strand into a stabilized elastomeric filament. This transition preserves the geometry established during extrusion or drawing and determines the resulting mechanical properties. Adjusting curing conditions therefore affects whether the filament retains dimensional accuracy while providing the flexibility and strength required for an engineered component.
Filament diameter directly influences the balance between flexibility, strength, and dimensional accuracy. A controlled opening and consistent drawing or extrusion help establish the intended strand size before curing fixes its shape. Managing diameter is especially important when fabricating customized geometries or integrating filaments into microscale systems, where small dimensional changes can affect component performance.
Material formulation and curing conditions jointly determine the properties of the finished strand. The formulation affects the elastomer’s baseline flexibility and strength, while curing stabilizes the polymer structure and filament geometry. Engineering these factors together allows a filament to be tailored for compliant structures, functional components, or prototypes that require a particular combination of mechanical response and dimensional stability.
A typical workflow begins by preparing uncured PDMS and moving it through a controlled opening by extrusion or drawing. The emerging strand is then subjected to curing so crosslinking stabilizes its shape and mechanical properties. Controlling the strand dimensions during formation and maintaining suitable curing conditions are central to producing a continuous filament with the intended geometry.
These filaments are useful when a prototype requires a compliant, elastomeric structure rather than a rigid component. Engineering applications described for them include soft robotics, microfluidic devices, stretchable interfaces, and customized geometries. Their fabrication route supports rapid integration of flexible material into prototypes and microscale systems, making them relevant when shape and mechanical compliance must be designed together.
The process can provide continuous elastomeric structures with controlled dimensions and tunable mechanical behavior. By managing filament diameter, material formulation, and curing conditions, engineers can influence flexibility, strength, and dimensional accuracy. These outcomes support the construction of functional components and compliant features in microscale systems, where the filament must both follow a designed geometry and retain it after curing.
