Electrochemical biosensors detect the binding of a target molecule by sensing an oxidation-reduction event. These sensors paved the way for modern biosensing after the invention of the glucose biosensor. This video will introduce electrochemical biosensing, show the workings of the glucose biosensor, and discuss how electrochemical biosensors are used in cancer detection.

Filtration and Urine Formation

The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys. Blood enters the renal...

Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Electrical resistance is the ability of an electrical circuit element to resist the flow of electricity. Resistance is defined by Ohm's Law: (Equation 1) Where is the voltage and is the current. Ohm's law is useful for determining the resistance of ideal resistors. However, many circuit elements are more complex and can't be described by...

Glomerular Filtration: Net Filtration Pressure

Glomerular filtration, a key process in the kidneys, is regulated by three main pressures: Glomerular blood hydrostatic pressure (GBHP), Capsular hydrostatic pressure (CHP), and Blood colloid osmotic pressure (BCOP). GBHP, with an average value of 55 mmHg, promotes filtration by pushing water and solutes through the filtration membrane. This is balanced by two opposing forces: CHP, a "back pressure" exerted against the filtration membrane by fluid already in the capsular space and renal tubule,...

FAQs
The applied voltage does more than move charged material. It drives oxidation or reduction at the electrodes, while the resulting electric field can change contaminant charge, encourage coagulation, or generate reactive species. These effects can make contaminants easier to separate or treat before they leave the treatment zone, linking electrochemical chemistry with physical retention.
The electrodes provide the sites where electrically driven chemical reactions occur, whereas the porous or membrane filter physically retains particles. Because these functions operate together, the system can address both suspended solids and dissolved pollutants. The electrochemical component helps modify contaminant behavior or promote treatment, while the filter supplies the physical separation step.
Combining the steps allows chemical and physical treatment to occur within one integrated process. Oxidation, reduction, charge changes, coagulation, or reactive species formation can improve the separation of contaminants that a filter may not retain directly. This arrangement can strengthen contaminant control while reducing chemical inputs and operational complexity compared with managing separate treatment functions.
A typical operation brings the contaminated fluid into contact with an electrode-equipped filtration system, applies a voltage, and passes the fluid through a porous or membrane filter. Electrochemical reactions occur at the electrodes while the filter retains particles. The electric field may also alter dissolved contaminants or promote coagulation, supporting treatment as the fluid moves through the system.
The approach can address wastewater containing suspended solids and dissolved pollutants, rather than focusing only on one contaminant form. Particle retention provides a route for removing suspended material, while electrically driven reactions and charge-related effects can improve treatment of dissolved contaminants. These capabilities make the method relevant to environmental protection and to producing water suitable for reuse.
Researchers may consider it when a treatment system needs to combine contaminant separation with electrically driven chemical treatment. Its environmental applications include wastewater treatment, suspended-solids removal, dissolved-pollutant control, and water reuse. The integrated design is especially relevant when reducing chemical inputs or simplifying operational steps is an important part of the treatment objective.
