Sažetak
Napredak u proučavanju biomedicinskih materijala i uređaja, posebno zavisi od primene efikasnih tehnika karakterizacije za procenu ključnih fizičkih parametara vezanih za performanse, oštećenja i kvalitet. Glavni cilj je uspostavljanje tačnih odnosa između makroskopskih funkcionalnih svojstava i nano(mikro) karakteristika. Brojni invazivni biomedicinski uređaji, na primer, planirani da ostanu u ljudskom telu tokom celog života pacijenta, jednom implantirani, deluju u jonskom okruženju krvi i u kontaktu su sa oslobođenim supstancama i ćelijama. Posledični efekti se moraju dodati ostalim faktorima starenja: dinamički stres pulsiranja je jedan od ovih efekata i tiče se rada samoproširujućih stentova instaliranih u arterijama, kao što je karotida, da bi se ispravila stenoza. Tehnike neutronskog snopa su odlično sredstvo za proučavanje materijala i delova od biomedicinskog interesa, doprinoseći rešavanju važnih pitanja povezanih sa metodološkim ograničenjima opšte prihvaćenih metoda analize: njihovi rezultati, komplementarno, mogu pomoći u poboljšanju kvaliteta i funkcionalnosti. Ovaj rad se bavi naprednom nano(mikro)-karakterizacijom biomedicinskih materijala i delova ovim nedestruktivnim i neinvazivnim nuklearnim metodama. Pominju se i neki primeri koji se odnose na biološko polje. Za primenu u biomedicinskom i industrijskom sektoru, Inženjerska kancelarija Rogante je razvila posebne metodološke pristupe i namenske postupke obrade i tretmana.
