EurekAlert!: New nanoparticles enable melanoma tumors to be removed with low-power laser light New nanoparticles enable melanoma tumors to be removed with low-power laser light A Northeastern University researcher has identified a way to target two of the deadliest cancer types, melanoma and triple negative breast cancer, with chemotherapy drugs but without the harms ... Melanoma usually appears in locations where the skin receives frequent sun exposure, like the face, neck, shoulders, arms and legs. These melanomas are often linked to ultraviolet (UV) damage and may ...
Context Explanation
Researchers at Oregon State University have developed and tested in a mouse model a new type of nanoparticle that enables the removal of melanoma tumors with a low-power laser. After the systemically ... The main source of natural light on Earth is the Sun. Historically, another important source of light for humans has been fire, from ancient campfires to modern kerosene lamps.

Insight Material
With the development of electric lights and power systems, electric lighting has effectively replaced firelight. Light is electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 −11 metres to radio waves measured in metres. Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference.
