Taking a closer look at unevenly charged biomolecules: Using Debye lengths, researchers improve sensor response to better analyze biomolecules

Clinicians most often monitor antibodies because these small proteins attach to antigens, or foreign substances, we face every day. Most biomolecules, however, have complicated charge characteristics, and the sensor response from conventional carbon nanotube systems can be erratic. A team recently revealed how these systems work and proposed changes to dramatically improve biomolecule detection.
