About

Photo Multiplier System using High Power, Pure Sinusoidal LED Driver with Temperature Stabilization Feedback

Case ID: UA16-209

Invention:
This patented technology uses a light emitting diode (LED) to achieve the same imaging results as a laser source, without damaging the tissues.

Background:
Laser sources are the current standard in fluorescent imaging techniques, but lasers can damage tissue samples over time. This technology is based on a technique used in high energy physics for scintillation counting, which optimizes the transient recording of fluorescence using the gating paradigm of photomultiplier tubes (PMT) for use in biology. Therefore, this technology is powerful enough to accomplish what current laser excitation can, without the tissue damage over time.

Status: This technology has two issued U.S. patents, #9,867,250 and #10,021,747

Key Benefits

The LED used in this prototype decreases the occurrence of degradation
LEDs have low power and broad spectrum relative to lasers
The absorption spectrum of LED can be better matched than lasers and
Capable of minimizing photobleaching
