Design of a Highly Sensitive and Specific Nucleotide Sensor Based on Photon Upconverting Particles

摘要

Phosphor/fluorescent molecules/particles have been widely used in various applications for quite some time.Typically,light with longer wavelength(s)is emitted when excited by shorter wavelength light,a process called downconversion.The opposite effect also exists,where a phosphor particle is excited with an infrared or red light and emits color(s)of shorter wavelengths,a process called upconversion.
