2025
This article introduces a unique method for fabricating master molds with an air-vent hole to prevent air entrapment during viscous polymer casting, enabling the fabrication of gelatin microneedles with sharp tips. By reducing the casting volume of high-viscosity gelatin, thin-walled hollow pyramidal microneedles could also be fabricated.

We present methods for fabrication of patterned microstructures of vertically aligned carbon nanotubes (CNTs), and their use as master molds for production of polymer microstructures with organized nanoscale surface texture. The CNT forests are densified by condensation of solvent onto the substrate, which significantly increases their packing density and enables self-directed formation of 3D shapes.

The two-thermal annealing method enables the fabrication of thin films of type II semiconductor silicon clathrate. Post-synthesis treatments, including thermal pressing and reactive ion etching, were performed to improve the material properties. This approach provides an accessible pathway for fabricating tunable clathrate films suitable for next-generation electronic and photonic devices.

FAQs
The master pattern controls the mold’s replicated geometry and surface features, so its shape directly determines the fidelity of later cast components. A carefully prepared master allows the silicone to reproduce defined structures accurately. This relationship is especially important in bioengineering, where small geometric differences can affect the design of microfluidic devices, laboratory models, or tissue-engineering constructs.
Degassing removes trapped air from the mixed silicone before curing. Without this step, air pockets could interrupt contact between the elastomer and the master pattern, reducing the accuracy of replicated surfaces or leaving unwanted voids in the mold. Removing entrained air therefore supports dimensional fidelity and improves the reliability of subsequent casting.
Curing changes the mixed two-part silicone elastomer into a solid, flexible mold that can be separated from the master pattern. The mold must reach this cured state before removal, because separation occurs only after the material has solidified sufficiently. Proper curing enables the finished mold to retain the intended geometry during repeated casting.
The workflow begins with a master pattern and a two-part silicone elastomer. The components are mixed, placed around the master, and degassed to remove trapped air. After curing, the solid silicone mold is separated from the pattern. This sequence produces a reusable negative form for making components with the master’s geometry.
Silicone molds can shape polymers, hydrogels, and other biomaterials into defined geometries. This versatility allows one mold design to support different experimental materials without changing the replicated pattern itself. The approach is useful when researchers need customized components for biological models, microfluidic systems, or tissue-engineering work.
Researchers use these molds when they need precise, customized geometries for prototyping or repeated component production. Applications include microfluidic devices, tissue-engineering constructs, and laboratory models. Because the molds combine dimensional fidelity, flexible separation, and repeated use, they can help investigators produce research components efficiently while exploring biological system designs.
