We present two processes for the microfabrication of porous polymer chips for three-dimensional cell cultivation. The first one is hot embossing combined with a solvent vapour welding process. The second one uses a recently developed microthermoforming process combined with ion track technology leading to a significant simplification of manufacture.

The fabrication of BioMEM devices is often done using a microfabrication technique called photolithography. This widely used method utilizes light to transfer a pattern onto a silicon wafer, and provides the basis for the fabrication of many types of BioMEM devices. This video presents the photolithography technique, shows how the process is performed in the cleanroom, and introduces some applications of the process.

A quantitative method to study spontaneous migration of cells in a one-dimensional confined microenvironment is described. This method takes advantage of microfabricated channels and can be used to study migration of large number of cells under different conditions in single experiments.
FAQs
Microfabricated culture chips regulate experiments by combining microfluidic channels with patterned surfaces and localized delivery of nutrients, gases, or chemical signals. This arrangement lets researchers control where cells experience particular conditions and how those conditions are presented within the culture environment. Fine spatial control is especially useful when cell behavior or organization depends on neighboring regions or changing stimuli.
Channel design and surface patterning serve different control functions. Channels guide fluids and support the delivery of culture inputs, while patterned surfaces establish defined locations or arrangements for cells or microorganisms. Together, these features connect physical organization with environmental control, allowing experiments to examine how spatial placement and supplied signals influence biological behavior within a small culture format.
Small sample volumes are not only a scale reduction; they also make it practical to regulate culture conditions with limited materials. Because nutrients, gases, and chemical signals can be delivered within the engineered environment, investigators can adjust experimental inputs while conserving reagents. This combination supports more controlled comparisons of cellular or microbial responses to defined conditions.
An experiment's outcome can reflect both the biological stimulus and its spatial presentation. Nutrient availability, gas delivery, chemical signals, channel layout, and surface patterning can each alter the conditions experienced by cultured cells or microorganisms. Considering these variables separately helps researchers interpret whether an observed response arises from the signal itself, its location, or the surrounding culture environment.
An integrated workflow can place culture, stimulation, and analysis on the same chip. Researchers establish cells or microorganisms in the chip's engineered spaces, control delivery of nutrients, gases, or chemical signals, and then examine the resulting biological response. Keeping these functions together allows controlled exposure and analysis to occur within one platform, linking experimental conditions directly to observed outcomes.
Microfabricated culture chips may use polymers, glass, or silicon together with microfluidic channels and patterned surfaces. These materials form the physical platform for maintaining cultures and organizing fluid delivery. In practice, the design must support the required culture environment, spatial arrangement, controlled exposure to biological inputs, and integration of analysis within the same experimental device.
Biologists can apply these platforms to several questions rather than a single culture model. They support studies of cell behavior, tissue organization, host-microbe interactions, and responses to drugs or environmental changes. The same platform can connect controlled culture conditions with questions about organization, interaction, and response, while using small sample volumes and reducing reagent requirements.
