The patent-pending methodology and surface chemistry used in the manufacture of Sona's Gemini and Omni gold nanorods makes them perfectly suited for both in-vitro and in-vivo applications.

Point of Care Diagnostics

  • Lateral Flow Assays.
  • Detect more than one biomarker.
  • Distinct visual difference between test lines.
  • Scalable and cost effective.

Drug Delivery

  • Used as a carrier device to deliver payload(s) of drug molecules to cells, tissue, or organs.
  • High efficiency of the GNRs for delivering pain relieving agents over other nanoparticles.
  • Eliminates the genetic modification of target cells.

Photothermal Therapy

  • Nanorods absorb in the near IR, and generate heat when excited with IR light.
  • Nanorods can be conjugated with tumor targeting motifs and ingested. When a patient is exposed to IR light nanorods are locally heated, destroying only the cancerous tissue while leaving healthy cells intact.

Cell Imaging

  • Gold bio-markers with plasmonic resonance have many advantages.
  • Produce high image quality.
  • Yield both qualitative and quantitative data.
  • More intuitive for the health care practitioners to interpret.

Point of Care Testing

Point of care testing (POCT) is when a test is administered at the time of consultation with near-instant availability of results; allowing the practitioner to make immediate and informed decisions about patient care. Point of care testing allows a diagnosis to be made in the fastest possible manner, when traditional testing is typically conducted in a laboratory setting.

Where is POCT Done?
Point of care testing can be carried out at the bedside, or near the patient. Simplified, POCT is any testing performed in a healthcare environment which is not sent to a lab for results.

POCT can be performed in the following settings:

  • Hospitals
  • Urgent Care Clinics
  • General Practitioner’s Offices
  • Mobile clinics

The advantage of Sona’s lateral flow test (LFT) in detecting COVID-19 is that results are achieved after 15 minutes, and the administration of the test does not require the specific expertise of a health care professional.


Lateral flow assay kits (or assay tests) represent a variety of simple techniques in which an analyte is detected via its combination (conjugation) with a target molecule embedded in, for example, a paper strip or a dip stick. Typical applications include home-based medical tests such as pregnancy tests.

The technology for most test kits is based on a staged transport of a bodily fluid (saliva, urine, or blood) in which the fluid is wicked along the first stage to a second stage, the site of bio-chemical reaction indicator. The premise of most home-based tests is that as the analyte is absorbed and reacted, an area of the strip changes color in comparison to a control strip. Gold nanospheres (GNSs) have modernized many conventional colorimetric indicators due to the inherent sensitivity of the surface plasmon resonance (SPR). Tunability of SPR of GNRs brings in host of novel optical properties that were never attainable with GNSs e.g. large color variation in compact size regime; this feature opens up new possibilities of multiplexing to create LFA for both qualitative and quantitative analysis of multiple analytes.

Our advancements in gold nanotechnology have the potential to transform the diagnostic and medical treatment markets.
