The Essential Guide to Different Types of Microscopy Grids 1

Standard Grids

Standard grids are the most commonly used type of grids in microscopy. They are made of a thin layer of plastic or metal and are designed to hold the sample in place for observation under the microscope. These grids are available in various configurations, such as square or hexagonal shapes, and with different bar widths and spacing.

Quantifoil Grids

Quantifoil grids are known for their high-quality and precision. They are made of a thin layer of silicon nitride and feature small holes with specific shapes and arrangements. These grids are ideal for applications that require high-resolution imaging, such as cryo-electron microscopy and single particle analysis.

Holey Carbon Grids

Holey carbon grids are characterized by the presence of holes, which are typically filled with a thin layer of carbon. These grids are widely used in the field of electron microscopy for their ability to minimize background noise and provide excellent support for the sample. Holey carbon grids are especially suitable for imaging biological samples and macromolecular complexes.

Gold Grids

Gold grids are favored for their durability and conductivity. These grids are made of a thin layer of gold, which makes them suitable for applications that require efficient electron transfer, such as energy dispersive X-ray spectroscopy (EDS) and electron energy loss spectroscopy (EELS). Gold grids are also used in the study of metal nanoparticles and nanowires.

Titanium Grids

Titanium grids are designed for applications that require high mechanical strength and resistance to corrosion. These grids are made of pure titanium or titanium alloys, and they are commonly used in transmission electron microscopy (TEM) for their stability and reliability. Titanium grids are ideal for imaging dense or heavy samples that may cause damage to standard grids.

The development and use of different types of microscopy grids have significantly advanced the field of microscopy, allowing researchers to explore a wide range of samples with improved precision and accuracy. Whether it’s for biological research, materials science, or nanotechnology, the right choice of grid can make a significant difference in the quality of imaging and analysis.
