In addition to responding to current customer needs for various materials, reagents and intermediates by selling catalog chemicals and providing custom synthesis, SunaTech is building its expertise and tehnological foundation for its future business.
 
 
1. Building a Library of Luminescent Metal Complexes
 
Whether for proving OLED device designs or for optimizing a bioanalytical assay, more choices of the key materials help reach higher performance levels. Phosphorescent metal complexes are such key materials in OLED devices and in some bio-related applications. The high diversity of organic ligands, many of which are synthesized solely by SunaTech Inc. and are otherwise unavailable, enables SunaTech’s scientists to create a library of luminescent matal complexes. The library is getting bigger and taking shape. Visitor of our website may try to search some of these compounds and find their basic structural and spectroscopic data. Hopefully, it’ll become an important source for scientists and engineers of different areas. 
 
2. Bridging OLED with Bioanalytics
 
Organic fluorescent dyes play pivotal roles in many fields of life science research and medical diagnostics. Specifically they are used for protein staining, cell staining, in vitro / in vivo imaging and for various bioanalytical methods.
 
In some applications, the drawbacks of using organic dyes, such as easy photobleaching, poor photostability, small Stokes shifts, and short fluorescence life time etc., have been well recognized but tolerated. Recently emerging semiconductor quantum dots provide only part of the solution to certain applications in which the drawbacks of organic dyes have to be overcome. However, there is no generic approach to address these widespread problems of organic dyes.
 
Cyclometalated iridium(III) complexes are currently being used as phosphorescent dopants for both OLED display and OLED lighting devices. While the library of these luminescent complexes is expanding rapidly, only a few of them are currently incorporated into host materials and used in commercial devices. The fact that almost all of these colorful emitters have been designed, synthesized and evaluated solely for the purposes of OLED devices by organic electronics community makes these materials, either in use or abandoned, largely underutilized.
 
In partnership with Rubipy Scientific Inc., SunaTech Inc. has synthesized numerous luminescent metal complexes with various functional groups (SunaTM SunaCytoTM and SunaTagTM) and discovered a number of dyes with excellent photophysical and photochemical properties. These discoveries opened up vast opportunities for researchers to develop novel methodologies based on these dyes, as they can be used as luminescent staining, imaging and labeling reagents. Furthermore, it was proved that using luminescent metal complexes could be a generic approach to avoiding some disadvantages of using organic dyes.
 
 
Characteristics of SunaTM, SunaCytoTM and SunaTagTM:
 
  • High chemical, photochemical and electrochemical stabilities
  • No photobleaching
  • Multiple colors under a single wavelength excitation
  • Large Stokes shifts
  • Emissive under photo and electrochemial excitation)
  • Available in electronically positive, neutral and negative states
  • Molecular weights ~ 1000 Dalton
Ø
 
SunaTM, SunaCytoTM and SunaTagTM find uses in the following areas:
  • Protein staining for electrophoresis
  • Cellular imaging
  • Bio-labeling for various bioanalytical methods
  • Fluorimetric protein determination
 
3. Developing Specific Assays 
 
Using its proprietary luminescent dyes SunaTagTM, SunaTech Inc. is developing point-of-care immuno-diagnostics based on immunochromatography (lateral flow immunoassay) and electrochemiluminescence. Cardiac markers, such as Troponin I and H-FABP, are being targeted. SunaTech’s goal is to deliver a low-cost quantitative POCT platform.
