the gold nanoparticles (Au-NPs) they certainly have good potential, by virtue of their low cytotoxicity, their ability to withstand surface modifications induced by thiol-containing molecules, to immobilise a wide range of biomolecules (amino acids, enzymes, DNA) and for their high optical extinction coefficient.

Introduction Nanoparticles are, by definition, three-dimensional particles of nanometre (0-100 nm) size. In the field of ophthalmology, interest in them relates to the ability of some of them to......

Hyaluronic acid is a high molecular weight polyanionic polysaccharide with a typical spiral structure that gives it a particular ability to combine with water1 and excellent viscoelasticity. A ciò......

Carotid-cavernous fistulas (FCC) are abnormal communications between the carotids or branches thereof and the cavernous sinus (1,2). Although they represent a pathology of strict neuroradiological and neurosurgical relevance, they often......

Age-related macular degeneration (AMD) is the leading cause of severely reduced visual acuity in people over 60 in the western world. It is a complex disease that recognises several risk factors such as age, gender, race, light exposure, diet, cigarette smoking and vascular disease.

Recently, other elements seem to play an important role in the pathogenesis of the disease: variations in DNA sequences coding for complement factors, modifications of TMP-3 and activation of cytokines......
