There also are concerns about the increased use of nanotechnology—compounds thousands of times smaller than the width of a human hair. Because of their size, there’s potential for these nano-sized ingredients to penetrate human cells and tissues. The technology is already being used in anti-aging creams and sunscreens—but the labels don’t have to specify its use.

Risks in architectural applications of nanotechnology - Nanowerk LLC, US
Already, dozens of building materials incorporate nanotechnology, from self-cleaning windows to flexible solar panels to wi-fi blocking paint. Many more are in development, including self-healing concrete, materials to block ultraviolet and infrared radiation, smog-eating coatings and light-emitting walls and ceilings. Nanotech is also starting to make the “smart home” a reality.
What will the consequences be as buildings become increasingly intelligent and nanomaterials become an everyday part of the buildings that surround us?
