LamdaGen offers its patented nano-structured metallic thin-film sensors as powerful biosensors for precise and rapid diagnostic applications in human and animal health, food & beverage safety, and water & contaminant monitoring.
LamdaGen’s nano-structured thin-films are grown in flexible sizes ranging from micron to millimeter scale using the Company’s patented techniques. The highly scalable manufacturing process provides exquisite architectural control over the nano-structured films’ morphology thereby enabling the ability to fine-tune the plasmonic surfaces for optimum detection performance. Additionally, the sensor films have a pure, rich and characteristically intense ruby color which allows for precise digital imaging.
Beyond the sensors’ important optical features, the Company’s nano-structured gold films have additional advantages including compatibility with:
- a wide range of solvents, pH environments, high ionic strengths and temperatures
- various matrices including cell lysates, supernatants, sera, whole blood, urine, saliva, tears and milk
The sensors are stable, easy to handle and can be grown on various surfaces (e.g., glass, polymers, stainless, ceramics, etc.) and in any shape or dimension. The sensors are also cost effective, highly scalable, reproducible and easily functionalized using conventional techniques.
The patented surfaces form powerful biosensors with quantitative detection limits from (~0.03 ng/mL or ~30 PPT, model dependent) and offer rapid real-time detection (10-20 minutes) of biomolecular interactions through precise monitoring of light interacting with the nano-structured surfaces.
LamdaGen provides a wide range of standard sized biosensors as well as customized sensor designs for convenient integration with existing product applications or next-generation products in development.
In general, LamdaGen’s biosensors offer remarkable performance coupled with design and sizing flexibility. Several systems including single, multiplexed and/or throughput configurations are shown on the right.

Frequently Asked Questions
At LamdaGen’s nano-fabrication facility, the Company’s manufacturing processes have been diligently altered and refined over the years into very specific protocols and procedures that ensure precise reproducibility of its nano-structured surfaces – sensor to sensor, chip to chip, batch to batch and month to month. Additionally, due the fact that the biosensors are manufactured as metallic thin-films, the stability of LamdaGen biosensors has been evidenced to exceed four years.
LamdaGen’s manufacturing processes and protocols are highly controllable, robust and reproducible. By precisely altering certain conditions, the Company has learned how to “grow” its LSPR continuous metallic films on almost any surface. Presently we are manufacturing for end users, including academic researchers, on many polymers, ceramics, as well as stainless and glass for a multiplicity of uses. Recently we are also growing films on selected membranes and filters for use in the area of diagnostics. Contact us for custom requests.
LamdaGen’s LSPR biosensors are a continuous metallic thin film which is characterized by a variety of unique physical, optical, and electrical properties that can be precisely controlled and tuned during manufacture for specific uses. These patented nano-structured films are “grown” on most any surface (glass-polymers-stainless-ceramic etc) and to nearly any size, shape or geometry, again depending on need or use. Due to this flexibility, the Company’s robust biosensors are also quite scalable.
