Use of Solid Nanoparticles as Contrast Agent for Ultrasound Imaging
, 2018 The feasibility of using solid nanoparticles as ultrasound contrast agent have been called into question on the ground that the size of a nano-particle is much smaller than the wavelength of ultrasonic wave, therefore, backscattering from these particles

Structure‐Property Relationships in Catecholamine Coatings for Broad Surface Functionalization
Advanced Functional Materials, EarlyView.Inspired by mussel adhesive proteins (MAPs), six catecholamine molecules with different molecular structure were systematically characterized and compared based on their ability to form homogeneous, reactive coatings. Highlighting candidates capable of balancing coating properties of interest, their successful use as primer layers for organic and ...
