Traditional Grids
Traditional microscopy grids have been widely used in biological research for many years. These grids are typically made of copper, nickel, or gold, and they come in various shapes and sizes. The most common grid shape is the square grid, but hexagonal and circular grids are also available. These traditional grids are suitable for a wide range of biological samples and can withstand the high vacuum and electron beam of the transmission electron microscope (TEM).
Quantifoil Grids
One of the latest innovations in microscopy grids is the development of Quantifoil grids. These grids are specifically designed to minimize the effects of beam-induced motion, making them ideal for high-resolution imaging and cryo-electron microscopy. The Quantifoil grids are made of a thin layer of silicon nitride with regularly spaced holes, providing excellent support for cryo-EM samples. The unique design of these grids allows for minimal background interference and improved image quality.
Graphene Oxide Grids
Graphene oxide grids are another recent advancement in microscopy grids. These grids are made of a single layer of graphene oxide, which provides an ultra-thin yet strong support for biological samples. Graphene oxide grids offer several advantages, including minimal sample charging, reduced background noise, and high conductivity, making them suitable for both TEM and scanning electron microscopy (SEM). The hydrophilic nature of graphene oxide grids also promotes better sample spreading and adhesion, enhancing imaging quality.
Advantages of Innovative Grids
The latest innovations in microscopy grids offer several advantages over traditional grids. For example, Quantifoil grids are designed to minimize beam-induced motion, which is a common issue in high-resolution imaging. This results in improved image quality and resolution, making these grids highly desirable for cryo-electron microscopy studies.
Similarly, graphene oxide grids provide enhanced conductivity and reduced background noise, allowing for clearer and more detailed imaging of biological samples. The hydrophilic nature of graphene oxide also improves sample adhesion and spreading, further enhancing the quality of microscopy imaging.
