A surgical instrument designed to destroy tissues with a concentrated light beam; such as, a laser.

A procedure in which tissue is destroyed by using a light beam; such as, a laser.

A substance which can change colors electronically.

Earlier prototype electronic inks could display just two color values (usually black and white); however, photonic ink can display any color value in the spectrum.

Among other applications, photonic ink can be used for refreshable, full-color images in an electronic newspaper, to coordinate pictures with updated newspaper content; as well as, in electronic books.

Photonic ink displays color through a controlled diffraction, a special type of interference which is responsible for the iridescent color effects of opals and butterfly wings.

A procedure in which steam is used to destroy tissue.

Removal (excision) of tissues or an organ by thermocautery; that is, excision with a heated wire or cautery.

1. The use of an actual cautery; such as, an electrocautery (cauterization by means of a hot wire or point) to burn away tissue during a surgical procedure.

Cauterization is the destruction (burning) of tissue with a hot instrument, an electric current, or a caustic substance.

2. Any form of agent or an instrument (a needle or snare) used to destroy abnormal tissue by burning, searing, or scarring, including caustic substances, electric currents, lasers, and very hot or very cold instruments.

A burning sensation in the chest.
