The question behind this study
This review surveys biomaterial microarrays for high-throughput screening of cell and tissue behavior. It connects chemical and physical control of 2D and 3D cultures with continual sensing in organ-on-chip models.
Screening cell environments over time
Cell and tissue behavior depends on material composition, three-dimensional arrangement, chemical environments and physical stimuli. This review organizes approaches to screening these conditions alongside sensors for continual observation in organ-on-chip models. It is distinct from an original study validating a newly fabricated integrated device or clinical predictive performance.
Combining material, chemical and physical cues
The review covers 2D/3D biomaterial arrays, contact printing and wetting patterns, and microfluidic gradients/perfusion for biochemical screening. Topography, stiffness, boundary geometry and active mechanical/electrical stimuli are physical screening variables. These examples combine conditions with cellular readouts, without generalizing model-specific primary-study findings to all cells and tissues.
Conditions for comparing platforms
The review summarizes fabrication and measurement from cited studies and has no independent Materials and Methods section. Comparisons need matched array scales, cell sources, culture dimensionality, stimulus timing, sensing intervals and endpoints. The underlying primary papers and supplementary information are outside this account’s scope, preventing a common ranking of throughput, reproducibility or sensor performance.
Connecting screening and sensing in organ chips
Organ-on-chip examples include optical pH/oxygen sensing, electrochemical sensing of secreted biomarkers, and continual observation using electrode regeneration. The review connects material/stimulus screening with sensing and identifies the need to combine them. Integrating high-throughput screening, dynamic microenvironments and continual sensing remained an open challenge at publication, not the review’s own experimental validation of a completed universal platform.
Regeneration and standardization limits
Finite electrode regeneration, PDMS drug adsorption and absorption, device size and complexity, and culture and analysis standardization remain concerns. Primary papers and separate supplementary information are outside this account’s scope; an absent link does not establish that no supplement exists. Figure 4’s actuation and strain wording remains unresolved, so it is described qualitatively. High throughput alone does not establish clinical predictive validity.
