Biophotonics• procedures and devices that use light technologies
• minimally invasive
• fewer complications
• less discomfort

Biophotonics: Endoscopes• help physicians see inside the body
• help perform surgeries without big incisions

Prenatal Care: Ultrasound• allows safe monitor fetus development
• uses sound waves
• long-term effects are unknown so it should only be performed when necessary during pregnancy
