Our Process

Our scientists understand that each assay being developed is unique with specific requirements, therefore, without knowing more about the test in question, only general development deliverables and associated pricing can be provided.


Working with nanoComposix has been equivalent to having an entire outsourced R&D Department rather than simply working with a CRO. In addition to performing lateral flow assay development internally, nanoComposix has recommended and overseen ancillary research by third party CROs to meet the objectives of our assay development program. The entire nanoComposix team has consistently exceeded my expectations with regards to both research and development and planning for commercialization of the resulting diagnostic technology. I would highly recommend that any business strongly consider nanoComposix for lateral flow assay development.

After evaluating numerous labs, I spoke with nanoComposix and their enthusiasm and expertise pushed them to the top of the list. Their critical thinking and ingenuity lead to a solution in dramatically less time than was expected. Their team was very collaborative, providing regular updates and an open line of communication throughout. I would recommend them to anyone looking for a partner in assay development.

Ben Noonan · President and Founder · Noonan Holdings

We recently contracted nanoComposix to develop a proof-of-concept lateral flow assay for therapeutic drug monitoring. NanoComposix worked on the project as if it was their own and not a contract R&D project, which showed their commitment and enthusiasm. We were thoroughly impressed with their meticulous approach in planning, designing and executing the project. Weekly updates were provided to ensure that the project was progressing within the prescribed timeframe. The team at nanoComposix demonstrated a very high degree of scientific knowledge and technical expertise to successfully develop a working assay for us. We will definitely use nanoComposix lateral flow assay development services for all our future needs.

Case Studies

Development of food safety assay using novel nanoparticles
Case Study: Fortune 500 packaging company

The existing standard method of detection for this food safety assay requires multiple days and a skilled scientist to perform the test. Using ultra-sensitive nanoparticle technologies, nanoComposix is developing a rapid lateral flow assay that can identify dangerous bacterial pathogens in less than 10 minutes.

Manufacture of validation lots of full rapid test kits under nanoComposix Quality Management System
Case Study: Non-profit organization developing assays for detection of neglected tropical diseases

Using the gold nanoshells, the non-profit group was able to achieve the desired sensitivity for their assay. The assay was transferred to nanoComposix for transfer to scale-up manufacturing under our Quality Management System which is based on ISO13485 and QSR (21 CFR 820). The assays were manufactured (50K strips) for testing in third world countries and are currently being evaluated in the field.

Novel particles used for assay development, helped reach the limit of detection
Case Study: Market leader in veterinary diagnostics

This customer turned to nanoComposix after three years of assay development where assay sensitivity could not be achieved by an internal team or with two separate contract assay development manufactures. The first company spent 6-months optimizing the assay and could not reach the required limit of detection. The second development company used proprietary nanobeads which achieved sensitivity but dried conjugate was unstable after 6 weeks. After a one-month effort, nanoComposix achieved the clinically relevant sensitivity using gold nanoshells.
