Biosensors

Biosensors allow the analysis of complex biological media. The detection of a large number of compounds is of great relevance, not only for scientific research but also for process control in the chemical and food industry. It is also indispensable in the healthcare field for the diagnosis and treatment of diseases and monitoring of illnesses. The pharmaceutical and biotechnology industries greatly desire frequent to continuous analysis of biological media.

Innovative Sensor Technology IST AG offers biosensors designed to measure the concentration of glucose, lactate, glutamine and glutamate in aqueous media. The biosensors use the enzymatic-amperometric measurement principle. They rely on immobilized enzymes to detect the target analytes with high specificity and reliability. Jobst Technologies GmbH, as part of IST AG, has developed an immobilization system that allows for adjusting parameters such as sensitivity and measurement range, thus meeting the requirements of different applications and customers. Furthermore, the technology is compatible with gamma and beta irradiation.

With many years of experience, IST AG also offers development of customer-specific applications in terms of technology development and consultation. As part of the standard development process, IST AG offers support at the point of implementation - this way we ensure the best solution for specific applications. 

We look forward to your individual biosensor request.

LV5 - Optimal for simultaneous and continuous multiparametric flow-through applications

The IST AG LV5 sensor is a flow-through biosensor and offers the possibility for multi-parametric measurements, since up to 4 analytes can be measured simultaneously (glucose, lactate, glutamine, glutamate). The sensor features a very small flow cell (1 µL) and therefore requires minimal sample volumes when used as an analyzer.

Further advantages of the LV5 biosensor include:

  • Excellent long-term stability over a month in continuous measurement mode (lifetime varies depending on various factors, including the analyte concentration and buffer system (medium) amongst others)
  • Long shelf life (under appropriate environmental conditions) 
  • Gamma and beta sterilization compatible
  • Suitable for continuous and analyzer measurement modes
  • Fast response time (depends on the buffer system (medium))
  • Reference, counter and blank electrodes on-chip
  • Integrated flow cell (various volumes)

The LV5 biosensor is suitable for sampling systems in laboratories or food and pharmaceutical industries.

Furthermore IST AG offers an evaluation kit for its biosensors:

Six Biosensor Transmitter - Evaluation Kit for Amperometric Biosensors

Our Six Biosensor Transmitter, developed by Jobst Technologies GmbH (an IST AG company), enables a direct evaluation of LV5 and IV4 biosensors. The Six Biosensor Transmitter can be directly connected to a computer via USB or to any microprocessor via a standard TTL-serial interface. The evaluation software bioMON is also available for the acquisition of measurement data and its analysis in real time.

Further advantages of the Six Biosensor Transmitter:

  • USB connectivity for easy evaluation
  • OEM version with serial interface for easy integration in custom developments
  • Very high current precision (approx. 20 pA)
  • 6 current channels with common reference and counter terminals
  • Current range can be factory-adjusted to meet specific requirements
  • Very light weight
  • Evaluation software bioMON available

IV4 - Optimal for stable continuous single parameter dip-in applications

The IST AG IV4 biosensor is a flexible stripe with large form factor ideal for direct dipping in the measurement media. It is designed for the detection of a single analyte, glucose as standard. This sensor is ideal for applications that require in-line continuous measurement with high reliability.

Further advantages of the IV4 biosensor include:

  • Excellent long-term stability
  • Long shelf life
  • Gamma and beta sterilization compatible
  • Fast response time and outstanding reliability
  • Reference, counter and blank electrodes on-chip

Given its compatibility with gamma radiation, the IV4 sensor can be used for example in bioreactors or aseptic media.
