Are you familiar with FLUORESCENCE ENHANCED THERAGNOSIS?

Fluorescence-enhanced Theranostics (FET) is an emerging field of research that combines fluorescence imaging and targeted therapy to diagnose and treat diseases simultaneously. FET utilizes the unique properties of fluorescent probes to provide real-time imaging of disease-specific biomarkers and deliver therapeutic agents to the targeted tissues or cells.
FET has several advantages over traditional diagnostic and therapeutic approaches. It enables real-time imaging of disease progression and treatment response, which allows for personalized treatment plans. FET also allows for the precise targeting of therapeutic agents to diseased tissues, reducing off-target effects and minimizing side effects. In addition, FET can be used to monitor the delivery and distribution of therapeutic agents within the body.

Sorry, no.

First of all, the term "Theranostics" should be better written with a "g" as "Theragnostics", as being justified by a paper ( Frangos S and Buscombe JR: Why should we be concerned about a ‘g’? Eur J Nucl Med Mol Imaging 46: 519, 2019). 
 Secondly, fluorescence imaging is often unreliable, because the intense of the fluorescence is influenced by multiple factors, and unnecessarily proportional to the amount of the fluorescent substance. By contrast, radionuclide-labeled tracers are more quantifiable and reliable for enhanced theragnostics.

No I'm not familiar with FLUORESCENCE ENHANCED THERAGNOSIS

Yes, I use computational methods for determining dose distributions and DNA damage yields when Auger and alpha emitters are used to irradiate biological tissues.  This methodology serves as a first stage for evaluating isotopes with potential for being used in targeted radionuclide therapy (theranostics).
