Understanding Monolayers and Their Applications

The video explores the science of surface coatings, focusing on monolayers and their applications. It introduces Langmuir-Blodgett films, developed by Katherine Blodgett, which enhance optical clarity. The video also covers self-assembled monolayers (SAMs), pioneered by Jacob Sagiv, and their role in nanotechnology. SAMs have diverse applications, including in electronics, medical devices, and biological research. The video highlights the Kavli Prize winners for their contributions to nanoscience.

What is the primary characteristic of a monolayer?

• It is a single nanometer thick.

• It is a single cell thick.
