A useful tool to analyze the effects of drugs, growth factors, and/or manipulated cells in an animal model of wound repair is described. This technique utilizes the properties of a polyvinyl alcohol (PVA) sponge to deliver and contain the desired treatment and also provide a platform to be excised and analyzed.

We present a protocol for preparing synthetic biomolecular condensates consisting of amphiphilic DNA nanostars starting from their constituent DNA oligonucleotides. Condensates are produced from either a single nanostar component or two components and are modified to sustain in vitro transcription of RNA from an embedded DNA template.

Nanoscaled sea-island surfaces composed of thermoresponsive block copolymers were fabricated by the Langmuir-Schaefer method for controlling spontaneous cell adhesion and detachment. Both the preparation of the surface and the adhesion and detachment of cells on the surface were visualized.
FAQs
Interconnected nanoscale voids create pathways through which molecules, ions, or fluids can enter, move, and contact internal surfaces. Transport therefore depends on the accessibility and arrangement of the pore network, not only on the material’s outer dimensions. This internal architecture helps explain why these structures can support controlled transport, adsorption, and reactions at interfaces.
A removable template provides a temporary spatial framework during material formation. After the template is removed, the remaining structure contains a corresponding network of pores. This approach offers a route to engineer the internal architecture rather than relying only on spontaneous assembly, making pore organization an important design consideration for applications that require accessible voids or controlled movement through the material.
The extensive internal surface exposes more material to molecules, ions, or fluids that enter the pores. This increases the number of accessible interfaces where adsorption, sensing, or catalytic interactions can occur. As a result, performance depends not just on how much material is present, but also on how effectively the nanoscale architecture makes its surfaces reachable.
One supported route begins with nanoscale building blocks that assemble into an interconnected architecture. Another uses a removable template to define the void network before the template is taken away. In either case, the process must preserve accessible pores and connected pathways, because those structural features determine whether molecules, ions, and fluids can reach the internal interfaces.
This architecture is useful when a material must expose substantial internal surface to substances moving through it. The pores allow molecules or ions to access interfaces throughout the structure, supporting adsorption and remediation research. Its low density can also help produce lighter materials, while the tunable pore network offers a way to adjust accessibility for a particular chemical environment.
Chemistry research uses these materials as platforms for catalysis, sensing, adsorption, and controlled transport. Their accessible interfaces can promote interactions with analytes or reactants, while the pore structure can influence how species move through the material. Related research also explores energy storage, remediation, and nanotechnology, where low density and tunable nanoscale architecture are valuable.
