Type-wise market taxonomy distinguishes DNA chips, protein microarrays, lab-on-chip (LOC), and tissue/cell arrays on the basis of biological probe immobilised and signal transduction modality. DNA chips, holding 41 % share, anchor the sector through dense oligonucleotide grids used for GWAS and oncological profiling, sustaining ASPs above USD 250 per slide. Protein microarrays (22 %) capture real-time antigenโantibody kinetics, enabling multiplexed serology tests with lower batch variability than ELISA. LOC devices (26 %) embed pumps, valves and detectors on a single substrate, shrinking reagent consumption 100-fold for clinics facing reagent budget caps. Emerging organ-on-chip sub-segments within LOC are forecast to post 19 % CAGR as pharma outsources efficacy assays. Finally, tissue/cell arrays (11 %) provide spatial histopathology references, accelerating antibody validation. Collectively, these product archetypes define competitive positioning and capital intensity benchmarks across the Biochip Products and Services value chain.
