  • Illustrative schematic: a field guide to how Raman and Raman mapping verify photoanodes and photocatalysts for solar water splitting.

    Solar Water Splitting: A Raman Field Guide
    How Raman and Raman mapping verify BiVO4 photoanodes, solar-fuel photoelectrodes, and photocatalytic water treatment across ProTrusTech-featured research.
  • Illustrative schematic: a field guide to the SERS substrates ProTrusTech has helped validate, grouped by the problem each one solves.

    SERS Substrates: A Raman Field Guide
    A guide to the SERS substrates ProTrusTech has helped validate — paper, flexible, silicon, gold and dual-function platforms, grouped by the problem each solves.
  • In GeS the Ag modes at 110, 236 and 269 cm⁻¹ appear along the armchair axis; B3g at 210 cm⁻¹ only across it. Illustrative schematic; Can one rotation identify an unknown layered crystal?

    Four Unknown Semiconductors, One Question a Single Spectrum Can’t Answer
    An ordinary spectrum tells you a material is there. Polarized Raman and µPL on RAMaker tell you what it is — proven across four unrelated layered semiconductors, one independent lab, seven months.
  • One silver-nanowire platform, retargeted three times. Illustrative schematic; How did a pesticide chip become a COVID assay?

    NanoSE: How We Co-Developed a Dual-Readout Biosensor — From Pesticides to a Pandemic
    One silver-nanowire platform, two signals, three years — how Protrustech and Nanovie co-developed NanoSE from pesticide sensing to a COVID-19 assay.
  • Tryptophan bands at 737, 887 and 1579 cm⁻¹ separate the antigen; 1288 and 1646 report the helix. Illustrative schematic; What tells one spike protein from another, without antibodies?

    Label-Free SARS-CoV-2 Detection: Direct SERS Antigen and Antibody Biosensing
    Discover how 3D silver-nanowire chips and dual-Raman systems turn a 10 µL sample into an instant, label-free pathogen diagnostic — no antibodies required.
