Passive Multidirectional Illumination in Light-Sheet Flourecense Microscopy

Description:

 

Brief Description:

Multidirectional Illumination, Light-Sheet Fluorescence Microscopy, Stripe Artifacts Elimination

  

Technology

 

 

Problem:

Light-sheet fluorescence microscopy enables rapid scanning of biological samples to reconstruct a 3-dimensional image of the sample. However, images generally contain artifacts (shadows, stripes, etc.) that are caused by illumination inhomogeneity due to absorption or scattering within the sample. These artifacts can occlude observation of biological phenomena in a sample. Moreover, current products use expensive and technologically demanding instrumentation to address these issues.

 

Solution:

Researchers in Professor Douglas Durian’s laboratory in the University of Pennsylvania’s Department of Physics and Astronomy have developed methods to passively generate multidirectional illumination in a light-sheet imaging system using a light shaping diffuser. The outcomes include the elimination of optical artifacts, similar to those described above. An add-on device incorporating this method into an optical microscope would provide a cost-effective alternative to current prohibitively expensive stand-alone equipment. 

       

Applications:

•       3-D light-sheet fluorescent imaging of biological samples (tissue or cells)

•       3-D imaging of colloidal and granular materials for particle tracking (soil mechanics, flow behavior, and rheology)

 

Advantages:

•       Cost-effective multidirectional illumination

•       Elimination of optical artifacts in light-sheet fluorescence microscopy

•       Add-on device compatible with commercial optical microscopes

 

Stage of Development:

•       Prototype

•       Proof-of-Concept Data Generated

 

Intellectual Property:

Provisional Pending
