Mycobacterial pathogenic strategies remain poorly understood. The slow growth rate of most species, the impenetrable nature of the cell-wall, and the hazards of working with pathogens make mycobacteria difficult to study and are largely responsible for our poor understanding of these organisms. In this video we will demonstrate the technique of electroporation, which involves subjecting cells to a brief high electrical impulse to allow the entry of DNA. It is the most widely used method for...

In utero electroporation is an important technique for studying the molecular mechanisms that guide the proliferation, differentiation, migration, and maturation of cells during neural development. Electroporation enables the rapid and targeted delivery of material into cells by utilizing electrical pulses to create transient pores in cell membranes. Although electroporation has traditionally been used in in vitro studies, scientific advancements have now broadened its utilization to intact...
FAQs
The platinum surface provides active sites where reduction reactions can occur more effectively, including oxygen or proton reduction. These sites support the transfer of electrons to dissolved or surface-associated species, helping the cathode facilitate reactions required in environmental electrochemical systems. Improved catalytic performance can increase reaction efficiency without changing the broader treatment or monitoring process.
Environmental electrochemical systems often operate in chemically complex solutions that can degrade electrode materials. A platinum coating improves resistance to chemical corrosion, helping the cathode retain its functional surface during operation. Greater durability supports more stable electrode performance, reduces the need for maintenance, and makes the electrode more suitable for sustained water treatment, pollutant transformation, or sensing.
Applied current drives the electrochemical reduction of dissolved platinum ions at the cathode surface. As these ions are reduced, platinum forms a thin functional coating containing catalytic sites. The resulting surface combines the conductivity of the underlying electrode with platinum’s catalytic and corrosion-resistant properties, enabling subsequent reduction reactions in environmental electrochemical applications.
In water treatment systems, the coated cathode can facilitate reduction reactions that contribute to the transformation of substances in the water. Its catalytic surface may improve reaction efficiency, while corrosion resistance helps maintain performance in complex solutions. These characteristics make the electrode relevant to treatment designs intended to manage environmental contaminants through electrochemical processes.
They are useful when an electrochemical system must promote reduction reactions while operating in solutions that may challenge electrode stability. Platinum’s catalytic activity can support the conversion of pollutants, and its resistance to chemical corrosion helps preserve the working surface. The combination is relevant to environmental technologies focused on transforming contaminants rather than only detecting them.
In sensing systems, the catalytic surface can facilitate electrochemical reactions associated with environmental contaminants, supporting their monitoring. Stable performance is especially valuable when measurements occur in complex solutions, where corrosion could impair an electrode. By combining catalytic activity with durability, these cathodes can contribute to more reliable monitoring technologies and potentially reduce maintenance requirements.
