Observe what drugs do to living human tissue on a chip. The screening application layer that sits on every organ-on-chip platform — now mandated by FDA Modernization Act 3.0.
Phenotypic screening identifies drug candidates by directly observing what compounds do to living cells — morphology changes, metabolic shifts, toxicity signals, barrier integrity, functional responses — rather than targeting a single molecular pathway. When this methodology deploys on organ-on-chip platforms, you get physiologically relevant human tissue under perfusion flow, mechanical forces, and multi-cell-type architecture that static well plates cannot replicate.
PhenoChip names this convergence: the screening application running on the hardware platform. Every organ-on-chip company builds the noun. PhenoChip is the verb — what you do with it. This is the workflow layer that transforms microphysiological hardware into an FDA 3.0-compliant drug discovery tool.
pheno· from Greek phainein — "to show, to appear." Phenotype: the observable characteristics of a living system. | chip — microfluidic cell culture device simulating organ-level physiology under dynamic flow conditions.

FDA interim final rule due. Sponsors submitting NAMs-based safety packages get expedited review. Phenotypic screening on human tissue chips transitions from competitive advantage to regulatory standard.
The Opportunity
Why Screening Needs Chips. Why Chips Need Screening.
⬡
The Screening Problem
Traditional phenotypic screening runs on flat 2D well plates — no perfusion, no mechanical forces, no tissue architecture. Over 90% of phenotypic hits from flat plates fail clinical translation. The biology isn't real enough to screen against.
◈
The Chip Problem
Organ-on-chip companies build beautiful human tissue models, but the readout layer — how you systematically interrogate drug effects at scale — is the phenotypic screening application. Hardware without screening is a demonstration, not a tool.
⬢
The Convergence
Chip-based phenotypic screening solves both problems simultaneously. Physiologically relevant tissue interrogated by mechanism-agnostic observation. This is FDA 3.0 compliance in practice — the verb and the noun, unified.
