If bacterial contamination levels are high on certain fruits, then UVC technology alone may not be sufficient to achieve the desired level of effectiveness.
UV Light Used for In-vivo Activation of Disguised Peptides
Researchers used ultraviolet light onto the molecules through the skin to sneak biomaterials containing peptide signaling molecules into living animals.

UVC light, which cannot penetrate opaque, solid objects, can be effective in sanitizing surfaces. The technology, which has been around for several years, has been used to effectively sanitize food contact surfaces as well as drinking water and contaminated air.
It works on micro-organisms by destroying nucleic acid and disrupting their DNA. But the light did not affect the chemical or physical quality of the fruit in the study.
How DNA Responds to UV Light Revealed
Researchers at Montana State University have come out with a new report that explains how the DNA responds when it is exposed to ultraviolet light.

They found that the light can inactivate up to 99.9 percent of pathogens on apples and pears. However, listeria was more UVC resistant than E. coli. "If you have smoother skinned fruit, then this technology is really great. If the fruits are very rough and if the level of contamination is low, it also works quite well," Sablani said.

Research Indicates UV Light Aids Cancer Cells That Creep Along the Outside of Blood Vessels
Deadly melanoma cells can spread through the body by creeping like tiny spiders along the outside of blood vessels without ever entering the bloodstream, a new study reveals.

Rough surfaces of strawberries, raspberries and cantaloupe offer places where pathogens can literally hide, reducing the effects of UVC light. If bacterial contamination levels are high, then UVC technology alone may not be sufficient to achieve the desired level of effectiveness.

Research Says Narrow-Spectrum UV Light May Reduce Surgical Infections
Surgical wound infections remain a serious and stubborn problem, killing up to 8,200 patients a year in the U.S, in spite of major efforts to keep operating rooms sterile.
