A novel sealing protocol to produce water-tight silicone-based seals for membranes of Polydimethylsiloxane (PDMS) chip devices. Intended for labs setting-up chip models and small-scale chip platform development. We demonstrate the protocol using plastic and native tissue membranes. This procedure only requires PDMS, toluene, mold, membrane, and a vacuum chamber.

The present protocol describes the maceration and cleaning of cadaveric bone with a vacuum-sealed, hot water bath immersion technique. This is a low-cost, safe, and effective method to produce anatomical specimens for surgical planning and medical education as an alternative to three-dimensional (3D) printed models.
FAQs
An operculum provides a discrete closing structure, whereas a mucus-rich barrier creates a more organic seal and calcium carbonate adds mineralized reinforcement. These alternatives reflect different biological strategies for closing shell openings. Comparing them helps researchers relate the material and structure of a seal to protection, internal-condition maintenance, and the organism’s mode of shell defense.
Sealing matters because an opening can expose soft tissues to several simultaneous stresses. A completed or reinforced barrier helps limit water loss while reducing contact with predators, pathogens, and physical damage. The process therefore links structural protection with physiological stability: the seal is not merely a cover, but part of how the organism remains viable under environmental stress.
Calcium carbonate deposition gives shell sealing a mineralized component and places the process within biomineralization, the biological formation of mineral structures. Its importance extends beyond immediate closure because sealing can be studied alongside shell formation and repair. This connection helps explain how organisms maintain or restore protective coverings rather than treating each opening as an isolated injury.
Variation is expected in both the sealing material and the way protection is achieved. Some organisms rely on an operculum, others on mucus-rich organic material, and others on mineralized calcium carbonate. This diversity allows biology studies to examine shell sealing as a comparative trait, connecting organismal physiology with ecological pressures and evolutionary differences.
Researchers can use shell sealing to investigate how animal physiology responds to environmental stress and how protective coverings are formed or repaired. The topic also supports ecological and evolutionary research, because sealing affects exposure to water loss, predators, pathogens, and damage. These links make it relevant across organismal biology rather than only shell anatomy.
Mineralized sealing features can provide evidence for how shell-bearing organisms protected openings and maintained their coverings. Studying these structures alongside shell formation may help place protective strategies in a broader evolutionary history. The fossil record therefore extends shell-sealing research beyond living physiology, offering a context for examining how defensive and repair-related traits persist or change over time.
