The growth of neurons into networks of controlled geometry is of great interest in the field of cell-based biosensors, neuroelectronic circuits, neurological implants, pharmaceutical testing as well as fundamental biological questions about neuronal interactions. The precise control of the network architecture can be achieved by defined engineering of the surface material properties: this process is called neuronal cell patterning. Different techniques can be used to produce such surface patterns. We have chosen microcontact printing (μCP), because it is a comparatively simple and universal method for patterning biomolecules.

Urea is an important biomarker for diagnosing various kidney and liver disorders. However, many existing methods rely on invasive blood sampling, which can potentially harm patients. Saliva has been recently recognized as a noninvasive and easily collectible alternative to blood for urea quantification.

In situ monitoring of small molecule diffusion at solid-solid interfaces is challenging, even with sophisticated equipment. Here, novel chromogenic photonic crystal detectors enabled by integrating bioinspired structural color with stimuli-responsive shape memory polymer (SMP) for detecting trace amounts of small molecule interfacial diffusion are reported. Colorless macroporous SMP membranes with deformed macropores can recover back to the "memorized" photonic crystal microstructures and the corresponding iridescent structural colors when triggered by diffused small molecules.

A self-propulsion Janus gallium (Ga)/magnesium (Mg) bimetallic micromotor is designed with favorable biocompatibility and antimicrobial properties as a therapeutic strategy for periodontitis. The Janus Ga/Mg micromotors are fabricated by microcontact printing technique to asymmetrically modify liquid metallic gallium onto magnesium microspheres. Hydrogen bubbles produced by the magnesium-water reaction can provide the driving performance of up to 31.

Article Synopsis
- * The research explored how the shape and confinement of CAFs on specially designed surfaces influence their morphology and gene expression, finding that certain conditions led to changes toward more inflammatory and desmoplastic CAF types.
- * The findings suggest that the way CAFs are physically arranged affects their response to cancer therapies, suggesting that understanding CAF plasticity can help develop better treatment strategies.

The ability to precisely pattern cells and proteins is crucial in various scientific disciplines, including cell biology, bioengineering, and materials chemistry. Current techniques, such as microcontact stamping, 3D bioprinting, and direct photopatterning, have limitations in terms of cost, versatility, and throughput. In this Article, we present an accessible approach that combines the throughput of photomask systems with the versatility of programmable light patterning using a low-cost consumer LCD resin printer.
