Design of a multiple biosensor for molecules detection associated to emotions

¿What is a biosensor?

The International Union of Pure and Applied Chemistry (IUPAC), defines a biosensor:

Device that uses specific biochemical reactions carried out by isolated enzymes, inmune systems, tissues , organelles , or whole cells to detect chemical compounds typically by electrical, thermal, or optical signals.

Biosensor Components

Biosensors types

Applications

Glucose Levels Measurements

Drug detection

Toxines and pathogens detection on food

Diseases diagnostic

Why design a biosensor to monitor our emotions?

Every day people have stress having a phisical and mind inbalance, this results in esto results in missed work days, further impairment at work, and frequent use of health services.

Emotional state indicators

Is an hormone and a neurotransmitter.

Is associated with the brain pleasure system providyng joy and positive reinforcement.

Its level is low in people with Parkinson’s. The schizophrenia is associated with an excessive amount.

¿How is produced the dopamine of natural form?

  • Sleep 7-9 hours
  • Celebrate an achievement
  • Do excercise

Are a type of substance that produce in the Nervous Central System.

It takes action in the hungry situations, in the thermoregulation, and also influence in  the appearance of some emotions.

How is produced the endorphin naturally?

  • Laugh
  • Eat chocolate

.

  • Is a neurotransmition with an important role in the inhibition of anger and agression, modo, sleep and sexuality.
  • When spring arrives, serotonin increases causing a progressive happiness, and sexual stimulation 

Howis produced the serotonin Naturally?

  • Varied diet rich in tryptopan
  • Do excercise
  • Look for places with enough sun.
         
It is an hormone secreted by the adrenal glands. Is released in response to stress. Fight the infections. Regulate sugar levels in blood. Maintain blood pressure. Regulate metabolism, and the process which the body uses food and energy.

Objective Population

General Objective

Design a biosensor to detect dopamine , oxytocin , endorphin , serotonin and cortisol in human blood and sweat .

Specific Objectives

1.Determinate target biomolecules for the detection of the aforementioned molecules.

2.Design a biosensor capable of detecting at least three of the moleculs of interest.

3.Functionalize the biosensor

4.Design the miniaturized device

5.Design the interface interpretation of the results.

How will we do it?
