I am pleased to share with you that the DIY AFM is reported by the latest Nature Nanotechnology 10, 480 (2015) that the DIY AFM is assembled by junior high school student and successfully measure PM 2.5 particles.

Microscopes are awesome! They help us see things that are not visible to bare eyes. Optical microscopes can only see micro scale (1/1,000 millimeter) structures. However, you can explore nano scale (1/1,000,000 millimeter) world by Atomic Force Microscopes (AFM). Yet a stock-ready AFM usually costs hundreds of thousands of dollars to buy. Thus we are providing you a solution to make your own AFM optomechanical system out of daily used parts including optical pickup unit (OPU) in a DVD player and piezo buzzers in your watch. The total cost is between 500 to 1,000 dollars (AFM controller not included). Most of the traditional AFM systems use beam deflection method for monitoring the AFM probe, the low cost educational AFM directly use an OPU for the same purpose. This low cost educational AFM is originally designed and made by Dr. En-Te Hwu, Institute of Physics, Academia Sinica, Taipei, Taiwan. Idea of using circuit boards as structure: Sebastian Buetefisch.

Traditional AFM:

顯微鏡可讓我們看到肉眼無法觀察的結構,实在是太棒了!光學顯微鏡能看到微米等級(1/1,000釐米)結構,然而原子力顯微鏡更可讓我們看到奈米(1/1,000,000 釐米)結構。一般的原子力顯微鏡動輒數萬至數十萬美元,只有研究機構可以負擔得起。我們希望透過這次介紹,告訴大家如何利用身邊的元件,包括DVD Rom的光學讀寫頭以及你手錶裡面嗶嗶叫的壓電喇叭,來製作一套自己的奈米級原子力顯微鏡的光機系統,材料價格不超過1000美元(不包含控制器)。傳統原子力顯微鏡大多使用光槓桿原理,而教育型原子力顯微鏡使用像散式光路偵測探針位移,此教育型原子力顯微鏡由台灣中央研究院物理研究所胡恩德博士設計並製作。使用電路板作結構之概念源自:Sebastian Buetefisch.

The optomechanical part of the AFM system is assembled by students from junior high school attached to Tsinghua University. The AFM base is structured by 4 circuit boards which are fixed by solder.

這邊由北京清華大學附屬中學的國中學生來示範,如何自己動手組裝原子力顯微鏡的光學機構系統。底座由4片電路板構成,組起來的結構件使用銲錫固定。

Dear Prof. Hwu,

This is indeed an amazing idea. I am a graduate student at UIUC and I work on the control of MFP-3D AFM (Asylum Research). I'd be very happy to build your DIY AFM and develop controllers for it. Would it be possible for you to share your design files and schematic of interfacing electronics? My email is:

mayank.mbic@gmail.com

Also, what are the x-y stage resonant frequencies in your set-up?

Thanks in advance!!

Mayank

Your High Speed AFM is interesting, I am focus on HSAFM also. Let's discuss about this.

MayankB2 whoand3 hours ago

Thank you, Prof Hwu.

I'm more than willing to discuss the HS-AFM with you. Please let me know if you want to discuss sometime this week. I've provided my skype id to Peter and you in my last email.

Thanks again!!

Mayank

I remember that I sent you references already right?

whoand (author)  dvd33329 days ago

sure!

sir it is great pls sent me guide to electronic part can i cut off budget to 100$
whoand (author)  mihir.sahu.3555 hours ago

The AFM probe is still expensive, 20 USD is the cheapest AFM probe. You may rise the budget....

Dear Prof. Hwu,

This is really awesome work! Would you be so kind as to send me detailed building plans, along with the controlling software? I would like to use your DIY AFM for educational projects linked to a Professional Master's Degree in Physics Education, aimed at public high school teachers and, perhaps, also for starting my own research in AF microscopy.

I forgot to give you my e-mail in my previous request: marcos_verissimo at id dot uff dot br
