NOSUM project

Design and evaluation of a personal kit to prevent sexual assaults by chemical submission (noSUM). Funded by Ministerio de Salud dentro del Plan Nacional de Drogas. 2020I040

The objective of NOSUM project is to develop and evaluate an easy-to-use kit that allows the youth to be able to identify whether γ-hydroxybutyric acid (GHB) has been spilled in a drink of any nature or not.

GHB, also known as liquid ecstasy, is used as a recreational drug for its euphoric and socializing effects, but it causes drowsiness and, above all, it cancels the will of the person who ingests it, which causes a loss of consciousness of reality.

This compound, in addition, is rapidly metabolized in the body and is not detected in the blood or urine through systematic toxicological analyzes, so when the victim realizes what has happened and goes to a center for health, the drug is likely to be virtually undetectable, and proving chemical submission can be very difficult.

For this reason, GHB is one of the chemical substances most used in crimes intended to nullify the will of the victims.

Providing society, and especially women, with a rapid detection kit that allows them to know right away if the drink has been adulterated can help to guarantee their safety and complement awareness and education campaigns to end this type of assaults.

Tuning of detection systems and degree of acceptance of the kit

Validation of the effectiveness of the system in real environments to improve the design.

Study of aggressions by chemical submission risk perception.

How does NOSUM kit work?

Sample of fluorescence and color changes of solutions containing GHB.

The kit will allow detecting a change in color and/or fluorescence in those drink samples that have been adulterated. The sensor developed by MODeLiC works with both alcoholic and carbonated beverages, even when they are mixed. The kit is currently being improved to facilitate portability and use.

Project Phases


Tuning kits


Recruitment of volunteers


Handover of samples and feedback on improvements


Analysis of samples and analysis of data on risk perception


The final goal of the project is to make quick detection kits available to the whole society. However, the data shows that 93% of the victims are women. For this reason, during the development of the project we aim to at young women between 18 and 28 years old to get directly involved.

For the initial phase of the project, 150 women university students, between the ages of 15 and 29 will be selected for the initial phase of the project. The selected people will participate in an open training session in which they will receive 3 quick detection kits.
