Source: Fattahi, N., et al. Photodegradable Hydrogel Interfaces for Bacteria Screening, Selection, and Isolation. J. Vis. Exp. (2021)This video demonstrates the use of photodegradable hydrogels to isolate bacterial colonies within silicon microwell arrays. Bacterial cells are first loaded into microwells, encapsulated in a crosslinked hydrogel, and cultured into distinct colonies. Upon exposure to ultraviolet light, targeted degradation of the hydrogel enables selective extraction of individual...

The development of microbial communities depends on a combination of factors, including environmental architecture, member abundance, traits, and interactions. This protocol describes a synthetic, microfabricated environment for the simultaneous tracking of thousands of communities contained in femtoliter wells, where key factors such as niche size and confinement can be approximated.

Chip-Based Digital PCR to Detect Rare Transcript Variants Using a Nanofluidic Chip

2025
This video demonstrates chip-based digital PCR — a variation of the digital PCR technique that is useful in detecting rare transcript variants. The PCR reaction is partitioned into the chambers of a nanofluidic chip, each of which acts as an independent reaction. The detection of fluorescence signals from the chambers with amplified targets confirms the presence of rare transcript variants in the sample.

Conventional methods to initiate suspension aggregate based cardiac differentiation of human pluripotent stems cells (hPSCs) are plagued with culture heterogeneity with respect to aggregate size and shape. Here, we describe a robust method for cardiac differentiation employing microwells to generate size-controlled hPSC aggregates cultured under cardiac-promoting conditions.
FAQs
These mechanisms move suspended cells or other biological samples toward available wells. Gravity can promote settling, while fluid movement or controlled flow directs the suspension across the chip and into confined spaces. The guidance mode determines how samples encounter open wells, making it central to achieving organized placement and consistent occupancy across the microscale device.
Physical confinement helps retain individual cells or small groups in defined locations during subsequent analysis or culture. By limiting movement between experimental units, the wells preserve spatial separation and support controlled observation of cell behavior or interactions. This organization is especially useful when researchers need parallel measurements or want to maintain defined co-culture arrangements.
Consistent occupancy depends on how effectively the applied suspension is guided toward and retained within open wells. Fluid movement, gravity-driven settling, or controlled flow can each influence placement across the chip. More uniform occupancy improves the reliability of measurements because experimental units are distributed more consistently rather than concentrated in only some regions.
The same confined-well format can accommodate individual cells or small groups, allowing researchers to match well occupancy to the experimental question. Single-cell arrangements support measurements focused on individual behavior, whereas small populations enable investigation of interactions within a confined unit. This flexibility extends the technique across multiple microscale assay designs without changing its spatial organization.
A typical workflow begins with preparing a suspension containing the cells or other biological sample and applying it to the chip. Fluid movement, gravity-driven settling, or controlled flow then guides material into open wells. Once cells or groups are retained, the loaded chip can support analysis, culture, screening, or controlled co-culture experiments.
Organized occupancy creates parallel, spatially separated experimental units for examining cell behavior, interactions, and responses in a microscale setting. Because each well provides a defined location, researchers can compare multiple units across the same chip. Consistent loading strengthens measurement reliability and supports development or evaluation of microscale assays.
Researchers can use this approach when experiments require parallel handling of cells, single-cell or small-population assays, or controlled co-culture studies. It is also relevant to screening and microscale assay development, where many confined units can be established on one chip. The method therefore connects sample organization with systematic analysis of cellular behavior and interactions.
Loading cells into defined wells can place individual cells or small groups within separate, confined experimental units. This arrangement helps researchers establish and maintain the intended local combination of cells while limiting mixing between wells. As a result, co-culture studies can examine interactions in an organized microscale environment and compare outcomes across multiple units.
