What we do

At Ferronova, we believe that accurate identification of sentinel lymph nodes (SLNs) can help guide detailed pathological staging of complex cancers. Our products are designed to help detect early stage cancer that would otherwise be missed by standard-of-care pathology analyses − supporting more accurate staging and less-invasive therapy for early stage solid tumours.

What is FerroTrace?

FerroTrace is a new super-paramagnetic iron-oxide nanoparticle (SPION) tracer designed to enable the surgeon to accurately map the lymphatic system with a laparoscopic or robotic camera. Used in combination with Indocyanine Green Dye (ICG), FerroTrace assists in the identification of sentinel lymph nodes for precisely targeted surgical excision.

FerroTrace takes the same path through the lymphatic system as metastasising cancer cells and is designed to be retained in the first draining lymph nodes − the sentinel lymph nodes. Designed to enable highly accurate detection of affected lymph nodes:

  • Before surgery – using MRI
  • During/after surgery – using the FerroMag magnetometer

How it works

Our unique patented technology is a new-generation, polymer-coated magnetic nanoparticle.

This nanoparticle drives a magnetically guided imaging system designed to precisely identify sentinel lymph nodes, to assist surgeons and pathologists to more accurately stage solid tumours and locate and address micro-metastases that may otherwise go undetected.

Current gastric cancer treatment lacks an effective strategy to tailor surgical and pathological assessment.

FerroTrace has tremendous potential to establish such a strategy, through novel techniques of sentinel lymph node biopsy.

What are the benefits

of using FerroTrace?

Compared with currently available tracers, FerroTrace is designed to be:
