ABOUT

Established in 2020, Guaranta Ltd is a microengineering consultancy for life sciences, MedTech and Biotech companies that have an R&D challenge related to microfluidics. We deliver technical designs and unbiased advice, so that R&D leaders don’t risk making wrong decisions when it comes to product manufacturing, be it at a prototype stage or high-scale manufacturing.

Founded and led by Dr. Nasr Esfahani who specialises in designing microfluidic and lab-on-a-chip products for life science, biotech and biomedical applications.

His experience in numbers:
• 20+ years R&D engineering experience
• 15+ years of experience in designing microfluidic devices
• 200+ development projects across different applications
• 22 peer-reviewed publications (including 2 Nature Methods papers)
• 11 patents

Why choose us?

WHY CHOOSE US?

The Guaranta services are tailored for R&D leaders who: 

  • Are developing innovative products for life science, healthcare or biomedical markets. 

  • Their technology includes miniaturisation, microfluidics or lab-on-a-chip elements. 

  • Want to decrease the risk of non-optimal product design in terms of product functionality and manufacturability.

 

We can support you throughout your product development cycle by providing technical designs and expert guidance. We help overcome challenges with product design, process development and manufacturing, so you can deliver your projects on-spec, on-time and on-budget.

Services

OUR SERVICES

Our services support you across different R&D stages of product development, from preparing technical designs for your prototypes to designing products and processes for mass manufacturing.
Being an independent consultancy, we provide unbiased advice on the design options, experimental validation, choice of materials and manufacturing technologies.
From Idea to Experiment

For those who have a product idea but need a technical design for a proof-of-concept or a prototype so it can get tested.

Integrated Microfluidics
(Lab-on-a-chip)

For those who want to integrate multiple processes into a miniaturized, multifunctional product.

Fluidic System Architecture

For those who need a comprehensive solution to control and automate fluidic handling in a microfluidic device.

Design for Manufacturing (DFM)

For those who want to minimize manufacturing costs while ensuring high product quality and reliability.

Micro- and Mass-manufacturing

For those who require micro-manufacturing tool sets or aim for mass production.

Set-up of Lab and Workshop

For those who are setting up an efficient laboratory or a workshop, in need of expert advisory, conceptual sketches and budget breakdown.
