SERS Substrate
Surface-enhanced Raman substrate with precisely controlled nano-cluster morphology. Batch-to-batch RSD < 5%, 10⁶–10⁹ signal enhancement, ppb-level detection limits on a 3 × 3 mm footprint.
Precisenova/English
Advanced micro-nano
interface solutions.
Precisenova (华琢微纳, Beijing) builds the full chain around the micro-nano interface: SERS substrates that make weak signals visible, Raman analyzers that identify complex samples in the field, custom microfluidic chips, and magnetic separation platforms that capture rare cells.
01 / PRODUCT LINES
Four lines, one chain
Handheld Area-Scan Raman
DMD-based high-frequency area-scan analyzer measures the averaged spectrum over a whole surface — solving mixture bias and missed-suspect problems. 159 × 79 × 42 mm, 690 g, 5.7-inch touch screen.
Portable Differential Raman
LenCyte DRS100. SERDS dual-wavelength acquisition strips fluorescence and stray light — accurate identification through plastic bags, paper and pigments. 784/785 nm, 200–2800 cm⁻¹, down to 1 s per measurement.
Custom Microfluidics
Design, fabrication and packaging all in-house. Maskless laser direct writing, injection molding and 3D printing combined; feature sizes from 1 cm down to 5 μm. Revised in the morning, tested the same day.
Patterned Magnetic Separation
Gradient magnetic fields from patterned micro-nano structures capture CTC, CPC and TIL via antibody-functionalized magnetic beads. Direct whole-blood loading, gentle elution, omics-compatible downstream.
AI Data Platform
Differential reconstruction, automatic identification and intelligent analysis on a cloud AI management platform. Database covers narcotics, pesticides and microorganisms, extensible per scenario.
02 / TRACK RECORD
Validated in top journals
Research enabled by our fabrication and device capabilities has been published in the following journals (among others).
03 / GROUP
Group structure
Precisenova operates through a wholly-owned subsidiary focused on the data side of the business.
Huazhuo Jiuzhang (Chengdu) Data Technology Co., Ltd.
A wholly-owned subsidiary of Precisenova, incorporated in October 2026 in Sichuan Tianfu New Area. It works on data governance, modeling and cloud platforms for measurement data.
