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.

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.

<p>Dear Dr. Hwu</p><p>A Happy Chinese New Year to you.</p><p>Thank you for this inspiring work!</p><p>I am actually thinking of the possibility to use your work as a long term project for junior/high school student. May I ask the permission and also the schematics, hardware components and maybe some of the software used to control the AFM and other details as requested by many others?</p><p>thank you again!</p><p>my email is hongjing.chung@gmail.com</p><p>best regards</p><p>chung</p>
<p>Simply outstanding. Could you send me the information of the electronics, code, etc. to my email </p><p>fads5235@gmail.com</p><p> Thank you!</p>
<p>Hello Sir</p><p> Its really a great project. Would you please send detail schematic,electronics and software used to control this AFM ?Thank you very much</p><p>email_id: babubinaya@ymail.com </p>
<p>Dear Dr. Hwu,<br><br>Ive just starting my Final Year Project on making an affordable AFM and you're project looks very similar to what I want to do. My intention is to use a different kind of control method in order to position the Z-axis, but I do not wish to design and make the stages (I don't have that much time :S)<br>It would be great if you could email me the schematics, hardware components and maybe some of the software used to control the AFM, thank you very much! :)<br>gasfhnsfazdrgzdf@mail.com<br><br>(Sorry about the weird email address, I didn't want to put my university email on a public comment)<br><br>Great project by the way, its amazing that you've managed to design this incredibly accurate system with very affordable components! :D<br><br>Cheers,<br>Charles<br><br></p>
<p>Hi Charles, please check your mailbox ;)</p>
<p>Dear Dr. Hwu,</p><p>I am a science teacher in North Carolina. Would it be possible to send me the schematics, material list, and any of the software used to create this AFM? Your project is absolutely amazing. I've been trying to build an AFM and having difficulties, and then I found your site.</p><p>Very gratefully, <br>Yours,<br>Duncan</p><p><a href="mailto:dmacpher@hotmail.com" rel="nofollow">dmacpher@hotmail.com</a></p>
<p>Sure!</p>
Can you provide me more information about it I would like to build one device like this.<br>milette.martin@gmail.com<br>thank you.

<p>Hello!</p><p>I am high school student and i wish to introduce your AFM to people, by making it. could you provide me the files or materials by email? it's woonjy2011/AT/gmail/dotcom.</p><p>also, do surrounding light sources affect the result? i mean, afm uses an photonic way to get datas, so are there noises from the environment? </p>
<p>oh, and thank you very much for great diy work.</p>
