What is scanning electron microscopy?4 answersScanning electron microscopy (SEM) is a powerful imaging technique used to analyze the microstructure of samples with high resolution and focusing depth. It involves accelerating electrons with high voltage and focusing them onto the sample, where electrons and material atoms interact. The resulting signals, including electrons and X-rays, are collected by detectors and converted into digital signals for display on a computer screen. SEM also allows for microchemical analysis using energy dispersive X-ray (EDX) feature. SEM has significantly higher resolution and focusing depth compared to optical microscopes. It is integrated with an energy-dispersive spectrometer for elemental analysis at the specimen surface. SEM imaging has been improved with the introduction of backscattered electrons and secondary electrons. Different components such as electron guns, magnetic lenses, and vacuum systems contribute to the unique imaging capabilities of SEM.
When was microscopy invented?4 answersMicroscopy was invented in the late 16th century, with the first compound microscope appearing in the Netherlands in the late 1590s. The original inventor of the microscope is not easy to identify, but evidence points to it being an invention of eye glassmakers in the Netherlands, possibly Hans Lippershey and Zacharias Janssen. The name "microscope" was coined by Giovanni Faber in 1625 for Galileo Galilei's compound microscope. Since then, microscopy has evolved significantly, with major inventions such as contrast, electron, and scanning tunneling microscopes arriving in the 20th century. These advancements have provided first-time views and information about biological structures and activity, opening up new avenues for disease therapies.

What are the specific health benefits of chlorine for gold fish?
5 answers
Chlorine has both positive and negative effects on goldfish health. On one hand, chlorine is widely used as a disinfectant in fish farms, with its efficiency and cost-effectiveness being key factors. However, exposure to acute chlorine toxicity can lead to various pathological changes in goldfish organs, such as gill edema, kidney degeneration, spleen congestion, and liver necrosis. Additionally, chlorine can improve the selectivity of catalytic reactions on gold surfaces, enhancing certain oxidation processes. On the other hand, chlorine toxicity can cause dyspnea, lethargy, and increased mucus production in goldfish, ultimately leading to hemolytic anemia and death. Therefore, while chlorine can have benefits in disinfection and catalytic reactions, its toxicity poses significant risks to goldfish health.

Scanning Ion Conductance Microscopy (SICM) has evolved as a pivotal tool for studying ion channels, leveraging its non-contact, high-resolution imaging capabilities to explore cellular and subcellular structures. The integration of SICM with gated ion channels into probes offers a novel approach for spatially resolved sensing at interfaces, as demonstrated by the use of dual-barrel pipettes where one barrel controls the pipette position and the second houses voltage-gated ion channels. This configuration allows for the imaging of local electric field gradients that activate TRPV1 channels near pores, showcasing the potential for ion channel-based sensing in imaging applications. Moreover, the development of dual-barrel membrane patch-ion channel probes (MP-ICPs) integrated into SICM systems has been shown to provide a revolutionary method for spatially resolved chemical sensing. This approach has been validated with different types of ion channels, including transient receptor potential vanilloid 1 and large conductance Ca2+-activated K+ channels, establishing the versatility of the method. The interplay between the SICM barrel and the ion channel probe (ICP) barrel has been studied, revealing that channel activity can be modulated by the SICM barrel potential, depending on the charge of the ligands gating the ion channels. Furthermore, the use of dual-barrel ion channel probes (ICPs) consisting of an open barrel for SICM imaging and a second barrel with a membrane patch for investigating ion channel activities has been described. This setup allows for the independent addressing of each barrel, enabling the study of the influence of ligand proximity on ion channel activation. These advancements underscore the utility of SICM in the study of ion channels, offering insights into their spatial distribution and activity, and opening new avenues for the investigation of cellular processes at the nanoscale.
What is the net rate of 3D imaging for time-lapse continuous data generated by 2pSAM (Two-photon Synthetic Aperture Microscopy)?
9 answers
The net rate of 3D imaging for time-lapse continuous data generated by Two-photon Synthetic Aperture Microscopy (2pSAM) can be inferred from advancements in two-photon microscopy techniques and the integration of various technologies aimed at enhancing volumetric imaging speeds and resolution. Two-photon laser-scanning microscopy, a precursor to 2pSAM, has seen significant improvements through modifications such as the use of electrically tunable lenses (ETLs) to rapidly image in 3D, achieving a volumetric imaging rate increase by up to four-fold. This modification allows for faster volumetric imaging by creating a tessellating scan pattern that repeats with the volume rate, thus facilitating the visualization of dynamics on timescales not achievable by traditional methods. Further enhancements in 3D imaging have been achieved through the application of adaptive optics (AO) to correct sample aberrations, which is crucial for deep 3D imaging of brain regions. Structured-illumination microscopy (SIM), although distinct from 2pSAM, demonstrates the potential for high frame rates over large volumes in live-cell imaging, achieving volume rates as high as 4 seconds in one color and 8.5 seconds in two colors. The development of algorithms for motion tracking and segmentation in biomedical image analysis also contributes to the efficiency of time-lapse continuous data generation by facilitating the validation and measurement of algorithm quality through synthetic datasets. Incorporating ETLs into adaptive spiral scanning algorithms has shown potential for achieving higher sampling rates, theoretically reaching up to 36.2 Hz, which represents a significant improvement over previous 3D scanning techniques. Novel measurement techniques capable of recording three-dimensional laser-induced images at high frame rates further underscore the rapid advancements in volumetric imaging. While the specific net rate of 3D imaging for time-lapse continuous data generated by 2pSAM is not directly stated, the integration of high-speed polygonal mirror scanners has led to substantial improvements in imaging speed, achieving scanning rates approximately 100 times faster than conventional scanning microscopes. This collective progress in two-photon microscopy and related technologies suggests that 2pSAM, by leveraging these advancements, would significantly enhance the net rate of 3D imaging for time-lapse continuous data, although the exact rate would depend on the specific configuration and implementation of these technologies within the 2pSAM framework.
