Sensors and sensorics 0600-S2-CKR-SS

Lecture:
IUPAC sensor definition. Chemical and physical sensors. Use of sensor measurements: off-line, at-line and in-line. Sensory analysis vs. advanced instrumental analysis. Functional parameters of the sensors: sensitivity, repeatability, selectivity, stability, reproducibility, response time. Biosensors as a special category of chemical sensors. Types of sensors due to the principle of operation: electrochemical (amperometric, potentiometric), resistive, resistive - catalytic, optical, capacitive, thermal, mass. pH electrode – metric as the oldest potentiometric sensor. Oxygen sensor according to Clark. Glucose sensor according to Clark as the first enzymatic biosensor. Glucose biosensors of the I, II and III generation. Advantages and disadvantages of enzymatic biosensors. Ion-selective electrodes. Optical biosensors. Biomarkers as natural biosensors for the detection of environmental contamination.

Laboratory program content:

2. -Assessment of air parameters - Assman psychometer
3. Determination of detection characteristics of commercial humidity sensors and resistive carbon sensors
4. Determination of chlorides in water by ion-selective electrode
5. Detection of traces of blood
6. Detection of metal traces on human skin and materials

Total student workload

Hours with the participation of teachers (50 hours): - participation in lectures – 10 hours - participation in the laboratory – 30 hours - consultations and work with an academic teacher – 10 hours Time spent on individual work of the student (75 hours): - preparation for the laboratory – 45 hours - student preparation for the exam – 30 hours Total: 125 hours (5 ECTS)

Learning outcomes - knowledge

Student: W1. Knows the concepts of chemical sensors K_W0 1 W2. He has knowledge of the classification of chemical sensors according to the type of transducer. K_W 03

Learning outcomes - skills

Student: U1: Can explain the principle of operation of individual chemical sensors - K_U0 1 U2: Can select the right sensor for a specific marking - K_U 05 U3:Work in a team, make commitments and direct their work – K_U03

Learning outcomes - social competencies

Student: K1: Can formulate and present opinions on chemical issues in forensic science and is aware of the importance of the acquired knowledge in solving problems - K_K01. K2: He is ready to take action on his own, he solves problems related to the profession of a chemist in a research laboratory - K_K03.

Teaching methods

Teaching methods giving: 1. information lecture (conventional) with the use of multimedia presentations. Teaching methods seeking: laboratory: laboratory – laboratory classes are related to the curriculum content processed during the lecture. The student performs the tasks independently after preparation based on the available instruction and recommended literature. Based on the observations made and the results of measurements, the student writes down the relevant reaction equations, performs calculations and draws conclusions.
