Bactometer, developed over 15 years of analysis, is a fast organic detector focusing on antimicrobial resistance in hospitals. Combining magnetic strategies with machine studying, it guarantees to curb the unfold of multidrug-resistant micro organism, considerably enhancing affected person outcomes.

Bactometer is a organic detector designed to bolster the combat in opposition to antimicrobial resistance in hospital environments.

It serves as an correct screening system, similar to superior strategies resembling PCR.

Not solely can the gadget produce ends in underneath an hour, however it is usually user-friendly, requiring no prior expertise akin to the COVID check. Its value aligns with that of laboratory cultures, a generally used but much less exact methodology on this area.

Technical Overview

The Bactometer’s progressive options stem from the incorporation of magnetic strategies and “synthetic intelligence” (machine studying), a departure from the optical strategies prevalent in most present applied sciences.

When it comes to methods it combines the next two:

  • Cell detection;
  • Nucleic acid (DNA, RNA) evaluation.

The employment of magnetic expertise makes the gadget impervious to pattern background interferences as there isn’t a presence of magnetic content material in organic matrices. Moreover, the magnetic labeling course of eliminates the usual time-consuming pattern preparation. The pattern goes via an computerized pattern preparation module have been the goal micro organism is captured and concentrated, adopted by a micro organism detection step. The final stage entails bacterial lysis, adopted by a patented approach to entice analytes on the sensor space, thereby enhancing our restrict of detection.
Bactometer was created because of the analysis that has been developed at INESC for the final 15 years (INESC MN and INESC ID), because the gadget integrates applied sciences ensuing from this lengthy analysis work.

The challenge was initiated and monitored by IST professors: Prof. Paulo Freitas, Prof. Susana Cardoso, Prof. Moisés Piedade, Prof. Jorge Fernandes, and Prof. Gonçalo Tavares.

Magnomics start-up members Dr. Filipe Cardoso, Dr. José Germano, Dr. Verónica Romão, and Sofia Martins additionally contributed to the gadget improvement.

The beginning…

Portugal 2022 eAwards

Bactometer challenge gained a ten.000€ prize at ‘Portugal 2022 eAwards’, awarded by the NTT DATA FOUNDATION. It represented Portugal within the World eAwards closing, held in Madrid (24 -26 October 2022). Though it wasn’t the winner, it was among the many 15 profitable tasks from Europe and Latin America which is a crucial achievement.

HiTech coaching

The challenge group participated within the 14-week HiTech commercialization program. This program is aimed toward analysis groups looking for steering to deliver the applied sciences developed within the analysis actions to the market.
This coaching was important for the challenge’s bounce begin, permitting the definition of the marketing strategy and the validation of the situation of best affect for the preliminary section of the gadget’s entry into the market – Intensive Care Models (ICU).

EIT Well being RIS Innovation

In January 2023 it was one of many winners of the EIT Well being RIS Innovation Name’ program which is able to enable the continuity of the challenge. This program presents entry to funding, mentoring, coaching providers, and networking alternatives to well being innovators from the Regional Innovation Scheme international locations.

Workforce and Expertise

The challenge group consists of 4 components:

  • Diogo Caetano (Electrical and Laptop Engineering PhD, from IST)
  • Ruben Afonso (finishing Electrical and Laptop Engineering PhD, IST)
  • Débora Albuquerque (finishing Biomedical Engineering PhD, IST)
  • Ana Rita Soares (Technological Physics PhD, from IST).

Each has its personal focus and duties throughout the challenge:
Diogo Caetano – Design of high-precision acquisition techniques for sensors (magnetic, within the case of the Bactometer).
Ruben Afonso – Growth of {hardware} to interface with sensors.
Débora Albuquerque – Detection of contagious ailments utilizing nucleic acid detection.
Ana Rita Soares – improvement of the magnetic Bactometer sensors, in microfluidics and within the organic labeling of the goal analytes.

Saving Lives

It’s estimated that multidrug-resistant micro organism trigger about 4.5 million hospital infections yearly in Europe. Day-after-day, sufferers colonized with multidrug-resistant micro organism who’re seen within the Intensive Care Models of hospitals for therapy of different acute situations introduce these microorganisms into the hospital surroundings. These microorganisms develop extra resistance and infect 1/5 of hospitalized sufferers.

Bactometer will enable fast and environment friendly identification of the pressure of micro organism and its resistance mechanisms, decreasing the present ready time of 48-72h (with the laboratory tradition methodology) to lower than 1h.

With the gathering of this info in a shorter time frame, it is going to be attainable to supply the affected person in a well timed method, elevated aseptic care (eventual isolation), and restrict the prophylactic use/abuse of antibiotics that has tremendously contributed to the rise of the issue. When used on the entrance in ICUs and long-term care amenities, Bactometer could be a device to rapidly and precisely diagnose AMR infections, permitting for isolation measurements to be applied in these organizations earlier than they can unfold to different sufferers. With much less contact, there’s much less likelihood of micro organism spreading, resulting in a discount in whole variety of infections, and consequently, fewer additional hospital days. A research carried out in 2020, confirmed that by reducing the unfold of AMR to decrease incidences, we might lower additional hospital days by greater than 40%.

These advantages could lengthen to society, each by way of the well being and high quality of lifetime of the customers, and by way of financial system, as it might lead to financial savings in technical and human sources. This challenge is an efficient instance of how expertise can contribute to fixing social and well being issues.

The gadget is presently being examined at CHULN (College Hospital Heart Lisbo Norte – Santa Maria Hospital) in partnership with ISAMB (Institute of Environmental Well being).
