This $4,000 Open Supply Excessive-Velocity Atomic Pressure Microscope Is a Nanoscale Imaging Marvel

A workforce of scientists from the Nationwide Taiwan College, the Technical Universities of Denmark and Munich, and the Physikalisch-Technische Bundesanstalt has constructed an open supply design for a nanoscale imaging high-speed atomic drive microscope (HS-AFM) — buildable for beneath $4,000.

“For the primary time,” says co-author Edwin Hwu of the workforce’s work, “you’ll be able to construct a Excessive-Velocity AFM and get 46×46µm, 512×512 pixels picture in 9.3 seconds. [This] low-cost HS-AFM can measure the nanotexture of human pores and skin corneocytes. Prices you lower than a Mac Professional!”

Constructing on an earlier design, Hwu and colleague’s controller design provides a doubling of imaging space and a hundredfold increase to its scanning velocity — offering the efficiency required for sensible use. To show it, the workforce used the device to evaluate the severity of atopic dermatitis (AD) in human topics — measuring the nanotexture of corneocytes, or “sexy cells,” the dimensions of which offers a sign of the regenerative capability of the pores and skin.

An atomic drive microscope works by way of contact: An ultra-fine needle is run throughout the floor of the thing to be imaged, bodily feeling its dimensions and reporting the consequence again to the host system for processing into a visual picture. Sometimes, such units are extraordinarily costly — however the model constructed by Hwu and colleagues is available in at $3,936 in components. Higher but, it’s launched beneath an open-hardware license for all to duplicate.

The workforce’s controller makes use of a Nationwide Devices myRIO-1900 FPGA improvement board related to the Arduino-based Strømlingo DIY AFM, a simplified atomic drive microscope design, and generates fast-axis and slow-axis scanning — upgrading the Strømlingo to high-speed operation.

“We imagine that along with engaged on simplified AFMs,” the workforce writes in conclusion, “[this] open supply controller can improve outdated AFMs to have high-speed DC mode measurements, thereby additional increasing the HS-AFM analysis neighborhood.”

The workforce’s work is revealed beneath open-access phrases within the journal HardwareX, with design recordsdata and supply code out there beneath the Inventive Commons Attribution 4.0 Worldwide license on OSF Residence.
