Abstract
Methods, systems, apparatus and machine readable media are disclosed to reduce biological carryover. An example method includes generating an alternating electromagnetic field and introducing an aspiration and dispense device into the electromagnetic field. The example method also includes inductively heating the aspiration and dispense device with the electromagnetic field to at least one of denature or deactivate at least one of a protein or a biological entity on a surface of the aspiration and dispense device.
Claims20
A method comprising:
- generating an alternating electromagnetic field having a frequency;
- detecting a characteristic of an aspiration and dispense device at least partially disposed in the electromagnetic field;
- dynamically adjusting the frequency of the electromagnetic field based on the characteristic to generate a modified electromagnetic field;
- inductively heating the aspiration and dispense device via the modified electromagnetic field to at least one of denature or deactivate at least one of a protein or a biological entity on a surface of the aspiration and dispense device.

A method comprising:
- generating an alternating electromagnetic field having a frequency;
- introducing an aspiration and dispense device into the electromagnetic field;
- identifying a characteristic of the aspiration and dispense device;
- determining a temperature at which to inductively heat the aspiration and dispense device to at least one of denature or deactivate at least one of a protein or a biological entity on a surface of the aspiration and dispense device based on the characteristic;
- adjusting the frequency of the electromagnetic field based on the temperature;
- and
- inductively heating the aspiration and dispense device via the electromagnetic field having the adjusted frequency.

A method comprising:
- generating a variable frequency current via an electrically conducting media;
- detecting a presence of an aspiration and dispense device relative to the electrically conducting media based on a temperature change or a load change with respect to the electrically conducting media;
- dynamically adjusting the variable frequency current based on the temperature change or the load change;
- and
- inductively heating the aspiration and dispense device via the adjusted variable frequency current to at least one of denature or deactivate at least one of a protein or a biological entity on a surface of the aspiration and dispense device.
