well, theoritically, it seems applicable although in vivo processing could amaze us with unexpected responses .. technology is a bifacial tool .. i guess we still remember that radiologic studies where found out to reveal pathologic lesion as neoplastic ones ..then it turned its homely face by inducing carcinogenesis itself!! so hoping too much is one of the MDs pitfalls .. this doesnt mean it shall not be followed up .. the up-side down turn of diseased humans' life worths every single trial ..whereas u may know that promotion of an already initiated carcinogensis is unpredictable , i.e. those nanotubules could be promoters themselves in certain cases .. all in all , i still think it is respect worthy the human brain that comes up with such great ideas, weighing both advantages & disadvantages of newly introduced applications , predicting even bizzare responses .. yup, a small p.s. for who commented "old people inventory" , cancer could be one of the leading causes of mortality, but its not the only one!! & saving lives shall be the representative goal of the medical profession never hesitated upon, fearing the burden of take-care of amnestic old people who could be our parents!!!!!!!!!!!!!!!!!
