Additive manufacturing of a precious bulk metallic glass

Roland Logé, Jamasp Jhabvala, Antonia Neels, Annapaola Parrilli, Güven Kurtuldu, Navid Sohrabi

For the first time, a high-density amorphous and crack-free bulk metallic glass (BMG) based on a precious metal (PdCuNiP) was produced via additive manufacturing (AM). Laser powder-bed fusion (LPBF) was used for the fabrication of the samples, and led to a ...

NIR-emitting and photo-thermal active nanogold as mitochondria-specific probes

Theo Lasser, Jérôme Extermann, Miguel Sison

We report a bioinspired multifunctional albumin derived polypeptide coating comprising grafted poly(ethylene oxide) chains, multiple copies of the HIV TAT derived peptide enabling cellular uptake as well as mitochondria targeting triphenyl-phosphonium (TPP ...

Fast detection of single nanoparticles in a microfluidic channel by a microlens array in combination with a conventional optical microscope

Martinus Gijs, Matteo Cornaglia, Hui Yang

We present the use of a microlens array in combination with a conventional optical microscope set-up for the detection of single nanoparticles (NPs) in fluid medium. Optically transparent dielectric microspheres are patterned in a microfabricated well arra ...
