Why SonanuTech

SonanuTech combines recent advances in photonic technologies, material science and nanotechnology to offer a quantum leap in speed and sensitivity for common biological assays.

Unique Technology

A variety of unique technologies that are covered by patents

Customized Solutions

A willingness to explore new application areas and work with customers to provide the best solution to their problems.


A wealth of research expertise and experience, with the backing of major research Universities


Our innovative Veloxi technology offers new possibilities for the detection of pathogens in foods, infections in human, markers of cancer, and DNA. It combines unique photonic and nanotechnology to yields limits of detection in the attomolar range and assay completion in minutes.

How Does it Work?

Phages specifically infect target pathogens such as food-borne salmonella or Staphyloccocus Aureus that could be antibiotic resistant. After infection, the phages multiply then lyse the bacterium to release many secondary phages.

These secondary phages are captured in a nanophotonic crystal device that enhances the fluorescence  signal from dye present in the dsDNA of the phages, offering superb sensitivity for our assay.

SonanuTech Offers

SonanuTech can offer extremely rapid assays using the Veloxi technology for pathogens that can be completed in less than two hours, without enrichment steps, and with the ability to detect down to about 5 to 10 CFU/ml of target bacteria.


Why Use Phosphor Nanoparticles

Our phosphor nanoparticles offer a gold shell on an up-converting core with up to 10x more brightness than particles without shells. The gold shell also offers a convenient platform for functionalization. A magnetic core can be added  to provide extraction and manipulation with simple magnetic racks.

SonanuTech can provide a range of wavelengths for a variety of different applications.


SonanuTech Inc. is a UC Davis startup that is bringing rapid diagnostics to the food and healthcare industry. We are looking for an energetic person to fill a six month contract position that requires expertise in microbiology and preferably with an interest in laboratory instrumentation. The successful candidate will work with the Principal Scientist to develop a method to detect phages. The duties include culturing and plating of phages, and quantifying phages by optical methods. The SonanuTech lab is located just outside Davis close the Yolo county airport.


The successful candidate will have in experience in most of the following areas:

  • Culturing and isolating bacteria or bacteriophages from growth media.
  • Characterization of bacteria and bacteriophages by plate counting.
  • Characterization of bacteria and bacteriophages by fluorescence plate reader.
  • Isolation and characterization of DNA/RNA from both bacteria and bacteriophages.
  • Developing experimental protocols.
  • Writing reports and operating procedures.

In addition, experience in the following would be advantageous:

PCR, electrophoresis, blotting techniques, knowledge of fermentation, microfluidics and optical instrumentation.


Minimum of a BS degree with some lab experience.

MS with lab experience is preferred.

The appointment is initially for six months from 1st July 2014. Remuneration will be consistent with the qualifications of the applicant. Review of applications will start in mid June with interviews to follow. Candidates can provide contact information and a very brief CV in the Comments box.
