Skin Testing for Drugs of Abuse
BioSens™ - Innovative On Site Device
Advantages
The BioSens™ Dynamic S System is an innovative, unique and biotech based technology that provides a quick, accurate and cost effective solution for drug testing.
Benefits include:
- 90 seconds to obtain a result.
- Tests for active drug compounds and not metabolites.
- Non invasive collection.
- Simple to operate.
- Individual result print out for each donor.
- Cost effective compared to urine and saliva.
- Tests for multiple narcotics simultaneously.
- Portable with PC connectivity.
Detectable drugs
The BioSens™ unit can test for the following classes of drugs:
- Cocaine
- Amphetamine
- Methamphetamine
- Ecstasy, MDA, MDEA
- Opiates, Heroin, Morphine, Codeine
- Marijuana.
Other drugs can be added as per your requirements.
Sample Collection
- Less invasive and faster than a urine collection (10 minutes).
- Cleaner and faster than a saliva collection (15 minutes).
- Collector wipes (5X) donor skin in one of the following areas:
- Back of the neck;
- Forearms.
- Collection takes 5 seconds.
- Collection pad preferentially absorbs target substances ready for desorption.
- Sample adulteration much harder than urine or saliva.
How Does the Biosens Work?
- The BioSens™ Dynamic S System utilises the displacement of antibodies from a coated piezoelectric crystal in the presence of the target drug.
- The crystal oscillates at a set frequency the magnitude of which is directly proportional to the mass of the crystal.
- The displacement of antibodies is monitored as an increase in the frequency of the crystal and is directly related to the concentration of the drug.
How Are The Drugs Detected?
Step 1 – Desorption
The filter is heated to desorb the collected substance by heating and then trapping the resulting vapours on a cold surface.
Step 2 – Extraction
The target molecules are removed from the cold surface by an innovative and efficient extraction method. An analyte is created which is transferred into the biocells for analysis.
Step 3 – Detection
The analyte reacts in the biocells and creates a frequency change if a target substance is present.
Step 4 – Result Delivery
The result is displayed in the text window on the Biosensor unit. A series of bars occurs next to each drug class indicating the relative concentration of narcotic in the sample. A "Clear" message indicates no drug has been detected. A "Hit" message indicates a presumptive positive for that drug class. A thermal printer can generate a hardcopy.
