Iron oxide and hafnium nanocrystals are two of the few successful examples inorganic used in a clinical setting. Although crucial to their application, aqueous surface chemistry is not fully understood. The literature contains conflicting reports regarding optimum binding group. To alleviate these inconsistencies, we set out systematically investigate interaction carboxylic acids, phosphonic catechols metal polar media. Using nuclear magnetic resonance spectroscopy dynamic light scattering,...
We recently introduced monoalkyl phosphinic acids as a ligand class for nanocrystal (NC) synthesis. Their metal salts have interesting reactivity differences compared to carboxylates and phosphonates provide cleaner work-up phosphonates. However, little is known about the surface chemistry of NCs with phosphinate ligands. Here, we probe relative binding affinity ligands respect other X-type perform competitive exchange reactions carboxylate phosphonate at hafnia, cadmium selenide, zinc...
Abstract Vascular corrosion casting is a method used to visualize the three dimensional (3D) anatomy and branching pattern of blood vessels. A polymer resin injected in vascular system and, after curing, surrounding tissue removed. The latter often deforms or even fractures fragile cast. Here, proposed that does not require corrosion, based on situ micro computed tomography (micro‐CT) scans. To overcome lack CT contrast between cast animals' soft tissue, hafnium oxide nanocrystals (HfO 2...
Here, we synthesized 2-ethylhexyl, 2-hexyldecyl, 2-[2-(2-methoxyethoxy)ethoxy]ethyl, oleyl, and n-octadecyl phosphonic acid used them to functionalize CdSe HfO2 nanocrystals. In contrast branched carboxylic acids, postsynthetic surface functionalization of nanocrystals was readily achieved with acids. Phosphonic capped were subsequently evaluated as memristors using conductive atomic force microscopy. We found that 2-ethylhexyl is a superior ligand, combining high colloidal stability compact...
In the surgical treatment of breast cancer, primary tumor is removed together with sentinel lymph nodes (SLNs). Current clinical procedures involve radioactive compounds (exposing both patient and surgeon) blue dyes, which often induce long-lasting skin discoloration. Here, we demonstrate in vivo detection SLNs mice using X-ray computed tomography (CT) near-infrared fluorescence via a dual-modality imaging probe. CT contrast provided by hafnium oxide nanocrystals, stabilized physiological...
<p>Here we synthesize 2-ethylhexyl, 2-hexyldecyl, 2-[2-(2-methoxyethoxy)ethoxy]ethyl, oleyl and <i>n</i>-octadecyl phosphonic acid use them to functionalize CdSe HfO<sub>2</sub> nanocrystals. In contrast branched carboxylic acids, post-synthetic surface functionalization of nanocrystals is readily achieved with acids. A simple flow coating process used deposit ribbons individual capped nanocrystals, which are subsequently evaluated as a memristor using...
We synthesized two resorcin[4]arene scaffolds with four phosphate binding groups. The superior affinity to nanocrystal surfaces is demonstrated using solution NMR spectroscopy and exceeds that of single phosphonates.
Vascular corrosion casting is a method used to visualize the three dimensional anatomy and branching pattern of blood vessels, guiding insight into health cardiovascular disease pathogenesis progression. A polymer resin injected in vascular system and, after curing, surrounding tissue removed. This process often deforms or even fractures fragile cast, resulting an overall loss information. Here, we propose that does not require tissue, based on in-situ high-resolution computed tomography...

In the surgical treatment of breast cancer primary tumour is removed together with so-called sentinel lymph nodes (SLNs), that have highest probability being invaded by cells. The current clinical standard to identify SLNs uses a combination 99mTc labelled nanocolloids and blue dyes. This workflow comes downsides such as inflexible procedures, exposure radioactivity, allergic side-reactions long-lasting skin discoloration. Here, we develop dual-modality imaging probe alternative demonstrate...
