Search indicated this has not been discussed. So into the fungal jungle of our toenails.
There are a whole bunch of snake oil sales sites dealing with this. From $50 to >$300. All pretty much say "trust us". Some claim to use lasers for heat and or LEDs. There is, however, real scientific research on the subject. I just started poking around. I have not found the correct Google magic words yet to find DIY projects on the subject. There has to be some.
Looking at one article (https://www.researchgate.net/public...on_photodynamic_therapy_blue_light_and_beyond) that goes through a bunch of other peoples results, it seems that a rough target is about 15 MW/cm of 254 nm UVC. A quick browse of Alibaba shows a bunch of diodes that could easily do that.
I would really like to take a shot at this, but I really would like to find some DIY experiences, or someone out there that knows a good bit about this. A good body of testing would go a long way.
Maybe get someone in China to make a Candlepower special device in a group buy.
If you are going to fix the problem with your toenails, you need to eradicate the toenail infection, then sterilize shoes, and common surfaces. All can be done with the UV. Perhaps in different forms. Smaller emission levels for toes, larger for shoes and surfaces. For the toes I think a constrained emission pattern would be needed to minimize exposure on surrounding skin. Rather like a small aperture penlight. Possibly rectangular light pattern for control and fast treatment.
The same approach (and possibly the same wavelength) also work for sterilizing wounds. Essentially a first aid light. And some effective eye protection.
There is at least one company that has a robot that has a real high power light source and can go into a room (think operating room) and sterilize the whole thing.
This might be an interesting activity for some of you LED guys to play with itty bitty wavelengths.
Does this interest anyone?
