The near-field scanning microwave microscope (NSMM) can quantitatively image materials properties at length scales far shorter than the free space wavelength(λ). Here we report a study of the effect of tip geometry on the NSMM signals. This particular NSMM utilizes scanning tunneling microscopy ...
Evaluation of microwave ablation in 4T1 breast tumor by a novel VEFGR2 targeted ultrasound contrast agents. Front Oncol 2021;11:690152. 105. Li XY, Xia SJ, Zhou W, Ji R, Zhan WW. Targeted Fe-doped silica nanoparticles as a novel ultrasound-magnetic resonance dual- mode imaging contrast ...
The dBSA-Au@Cu2S crystals formed with an average size of approximately 9 nm. There was a strong absorption in the near-infrared (NIR) field located at 1348 nm, and they exhibited low toxicity in the in vitro tests. Furthermore, we demonstrated that dBSA-Au@Cu2S could be used for ...
Citrate buffer 10mM at pH 0.6 in microwave (2 x 5 min at 750 W) was used for antigen retrieval. After three washes in 0.1M PBS pH 7.4, slides were blocked with 10% goat normal serum in PBS for 15 min at room PLOS ONE | www.plosone.org 5 October 2013...
Near-field microscopy overcomes the diffraction limit through the partial conversion of the evanescent fields, formed around the subwavelength sources of light, into propagating waves by interactions between the probe and the sample. Contrast parameters in this imaging technique are quite different from ...
L Gao,N Hagen,TS Tkaczyk - 《Journal of Microscopy》 被引量: 14发表: 2012年 Coherent Filterless Wideband Microwave/Millimeter-Wave Channelizer Based on Broadband Parametric Mixers is to analyze the spectral content of intercepted microwave and millimeter-wave signals over a very wide bandwidth in ...
In the microwave frequency range, tissue permittivity is dominantly determined by the chemical composition of tissue, i.e., different types of ions and molecules in the intracellular and extracellular space. As a result of the delay between the applied electromagnetic field and the tissue ...
(ROS) from biological environments, which is crucial in safeguarding these environments against radiation-induced damage. Additionally, the Ce atom’s high Z number makes it an ideal candidate for utilisation as an X-ray imaging contrast agent. We herein show how the injection of albumin-...
However, it should still be noted that, sometimes, changes in the probe state (because of possible events of some atoms jumping from the surface to the STM probe or vice versa, or due to the probe tip shape changing, caused by a strong electrical field applied between the probe and the ...
Owing to strong near-infrared absorption properties, the BGVs showed a higher photothermal conversion efficiency (37%) than GVs (18%), gold nanorods (22%) and gold nanoshells (13%). Figure 4. Biodegradable gold vesicles (BGVs). (A) Scanning electron microscopy image of BGVs (inset: 3D ...
