This study presents a methodology to prepare 3D, biodegradable, foam-like cell scaffolds based on biocompatible side-chain liquid crystal elastomers (LCEs). Confocal microscopy experiments show that foam-like LCEs allow for cell attachment, proliferation, and the spontaneous alignment of C2C12s myoblasts.

Here we describe a cost-effective technique for organotypic culture of adult porcine retina for seven days. Briefly, a sterile filter paper was used to lift the neural retina off from the RPE and place photoreceptor side up on an insert raised by a custom-made stand.
FAQs
As the liquid layer becomes thicker, electrons travel through a longer path before reaching the detector. This increases scattering and absorption within the liquid, which reduces the transmitted signal and can weaken image contrast. Consequently, thickness must be controlled closely when imaging features whose visibility depends on retaining sufficient electron transmission through the sealed cell.
The liquid is only one part of the electron path. Electrons also pass through the cell’s entrance and exit membranes, so scattering and absorption arise from the combined structure. A suitable design therefore considers the entire layered path rather than treating the liquid thickness as an isolated variable, helping preserve usable signal under liquid conditions.
A thicker liquid layer can provide more volume for realistic reactions, but the increased path length also causes greater electron scattering and absorption. A thinner geometry generally supports better spatial resolution and image transmission, while potentially limiting the available reaction environment. Engineering the cell requires choosing a thickness that serves both the experiment and the imaging requirements.
Thickness affects how much material the electron beam must traverse, linking cell geometry to radiation exposure management. A thin liquid path reduces the amount of liquid encountered by the beam and supports more manageable imaging conditions, while excessive thickness can compromise transmitted signal. This consideration is important when observing processes over time rather than capturing only one image.
Controlled thickness supports in situ observation of processes that change while liquid is present, including nanoparticle growth, electrochemical processes, and corrosion. These applications require a liquid environment that can sustain the relevant reaction while still permitting useful imaging. The resulting design allows researchers to examine dynamic behavior that would not be visible in a dry specimen.
Selection begins by balancing the liquid volume needed for a realistic reaction against the thin geometry required for spatial resolution, electron transmission, and manageable radiation exposure. The preferred thickness depends on the intended observation, whether nanoparticle growth, electrochemical activity, corrosion, or another dynamic process. This balance determines how effectively the sealed cell supports analysis under liquid conditions.
