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.
Printing Tiny Hydrophobic Corrals So Droplets Sit Still for SERS
An ionic-liquid electropolymerization route patterns hydrophobic wells on ITO and flexible film — droplet arrays for electrochemistry and SERS on the MRI.
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.
TCSPC Explained: What RAMaker’s Photon Counting Reveals
One measurement, two unrelated problems solved — how time-correlated single-photon counting on RAMaker separates real physics from simple brightness.
One Raman Scan Separates Oral Cancer From Healthy Tissue With 87.5% Accuracy
A ProTrusTech Raman system helped classify oral cancer from healthy tissue with 87.5% accuracy — no biopsy, no stain, just a laser scan.
One Nanochip Sees Two Ultra-Sensitive Signals — Where NanoSE Begins
Four pesticides, one fluorescent dye, and hot spots the researchers could actually photograph — the 2021 paper behind everything that came after.
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.
