Bases nanotecnológicas de una «nueva» Nefrología

After contextualising the generic frameworks of nanotechnology and nanomedicine, the 2 disciplines are discussed in the field of Nephrology. The potential downside to nanonephrology is the renal clearance of nanoparticles, the use of which is ever-increasing both for nanomedicinal purposes and in nanofoods. The positive impact of nanotechnology in Nephrology is centred on the development of renal nanodiagnostics for basic renal function studies, the early diagnosis of acute kidney injury, reliable and simple follow-up of chronic kidney disease and the improvement of magnetic resonance imaging. Renal drug nanotherapies comprise an important and dual-faceted area: The protection of drugs and nephrotoxic agents (e.g. antibiotics, antiretrovirals, contrast media, etc.) on the one hand, and the development of new kidney disease medications on the other. Renal 'nanotheranostics' is a promising but little-studied area. The impact of nanostructured supports on renal tissue regeneration is also discussed. The article concludes with a brief analysis of the various nanonephrology perspectives.
