Improvement of the stainless steel electropolishing process by organic additives

open access: yes, 2016
The influence of organic additives on the process of surface electropolishing of AISI 304 type steel was determined. Additives were selected in initial potentiodynamic tests pursuant to the plateau analysis on the current/potential curves. The assessment

Self‐ordered silver nanoparticles on nanoconcave plasmonic lattices for SERS multi‐antibiotic detection

open access: yesNanophotonics, Volume 14, Issue 15, Page 2605-2618, August 2025.
Abstract Antibiotic detection at trace levels in different matrices is an important tool for environmental monitoring, clinical diagnostics, and pharmaceutical quality control. Using aluminum concavities covered with silver nanoparticles (AgNPs), this study introduces another approach for the surface‐enhanced Raman spectroscopy (SERS) detection of ...

Controlled drug delivery from composites of nanostructured porous silicon and poly(L-lactide) [PDF]

open access: yes, 2012
Porous silicon (pSi) and poly(l-lactide) (PLLA) both display good biocompatibility and tunable degradation behavior, suggesting that composites of both materials are suitable candidates as biomaterials for localized drug delivery into the human body. The
