摘要： An extracellular vesicle characterization and analysis device in terms of their size, phenotype, and cargo content is provided. A method performed with the device to quantify the heterogeneity of extracellular vesicle samples both in terms of size and cargo content and further quantify the purity of extracellular vesicles based on their phenotype and cargo content is further provided. The extracellular vesicle characterization and analysis device includes an atomic force microscope and confocal Raman spectrometer subsystems that will present the phenotypic characterization and cargo analysis of extracellular vesicles, respectively. By processing the topographic images obtained by atomic force microscopy with image processing methods and analyzing them, the dimensional heterogeneity of the extracellular vesicle samples can be quantified and information about their purity can be presented. The confocal Raman spectrometer applies the tip-enhanced Raman spectrum method, performs a heterogeneity quantification and provides data on the purity of the sample.

摘要： A dialysis system is provided that includes a dialysis machine and a potassium sensing device that is configured to measure the concentration of potassium in the patient's blood, in spent dialysate resulting from treating the patient, or in both. The potassium sensing device can be configured to generate a sensed value of the concentration of potassium. A control and computing unit, including a processor and a memory, is configured to receive the sensed value, compare the value with one or more values stored in the memory, and generate a control signal based on the comparison. A potassium infusion circuit uses the control signal to infuse supplemental potassium solution into the treatment dialysate, a replacement fluid, or both. The memory can include stored patient-historical and population data.

摘要： A method for autonomously applying a dangling bond pattern to a substrate for atom scale device fabrication includes inputting the pattern, initiating a patterning process, scanning the substrate using a scanning probe microscope (SPM) to generate an SPM image of the substrate, feeding the SPM image into a trained convolution neural network (CNN), analyzing the SPM image using the CNN to identify substrate defects, determining a defect free substrate area for pattern application; and applying the pattern to the substrate in that area. An atom scale electronic component includes functional patches on a substrate and wires electrically connecting the functional patches. Training a CNN includes recording a Scanning Tunneling Microscope (STM) image of the substrate, extracting images of defects from the STM image, labeling pixel-wise the defect images, and feeding the extracted and labeled images of defects into a CNN to train the CNN for semantic segmentation.

摘要： The present disclosure relates to the technical field of microwave test, and discloses a method and a system for analyzing the spatial resolution of a microwave near-field probe and a microwave microscope equipped with the system, wherein in the method for analyzing the spatial resolution of the microwave near-field probe, a three-dimensional equipotential surface in a sample is drawn by using an electric field formula calculated by a quasi-static theory; an equivalent model of a probe sample is established by using finite element analysis software, so as to change material characteristics in the area outside the three-dimensional equipotential surface; by observing the influence of changing materials on the potential distribution in the sample, a near-field action range of the probe is determined, and the spatial resolution of the microwave near-field scanning microscope is analyzed and calculated.

摘要： The invention relates to a measuring device for a scanning probe microscope that comprises the following: a sample receptacle which is configured to receive a measurement sample to be examined; a measuring probe which is arranged on a probe holder and has a probe tip with which the measurement sample can be measured; a displacement device which is configured to move the measuring probe and the sample receptacle relative to each other, in order to measure the measurement sample, such that the measuring probe, in order to measure the measurement sample, executes a raster movement relative to said measurement sample in at least one spatial direction; a control device which is connected to the displacement device and controls the relative movement between the measuring probe and the sample receptacle; and a sensor device that is configured to detect movement measurement signals for an actual movement of the measuring probe and/or of the sample receptacle that is executed during the relative movement between the measuring probe and the sample receptacle in order to measure the measurement sample, and to relay the movement measurement signals to the control device, the movement measurement signals indicating a first movement component in a first spatial direction that disrupts the raster movement and a second movement component in a second spatial direction that disrupts the raster movement, which second spatial direction extends transversely to the first spatial direction. The control device is configured to control the relative movement between the measuring probe and the sample receptacle in such a way that the displacement device is acted upon by the control device with compensating control signal components which cause a first countermovement which substantially compensates for the first disruptive movement component in the first spatial direction, and/or cause a second countermovement which substantially compensates for the second disruptive movement component in the second spatial direction. Furthermore, a scanning probe microscope comprising the measuring device and a method for scanning probe microscopic examination of a measurement sample by means of a scanning probe microscope are provided.

摘要： Infrared (IR) vibrational scattering scanning near-field optical microscopy (s-SNOM) has advanced to become a powerful nanoimaging and spectroscopy technique with applications ranging from biological to quantum materials. However, full spatiospectral s-SNOM continues to be challenged by long measurement times and drift during the acquisition of large associated datasets. Various embodiments provide for a novel approach of computational spatiospectral s-SNOM by transforming the basis from the stationary frame into the rotating frame of the IR carrier frequency. Some embodiments see acceleration of IR s-SNOM data collection by a factor of 10 or more in combination with prior knowledge of the electronic or vibrational resonances to be probed, the IR source excitation spectrum, and other general sample characteristics.
