Fabrication of micromachined fountain pen with in situ characterization possibility of nanoscale surface modification
We present the fabrication process of a tool that can be used in standard atomic force microscope (AFM) for in situ characterization of chemical, chemical–mechanical or physical surface modification performed with the same device. The image obtained during scanning contains information about the modified and unmodified topographies for each scanning line, thus quantification of surface topograp...
متن کاملSpeech Pen: "WRITING" on Speech
本論文では音声認識と手書き文字認識を組み合わせ,講義・プレゼンテーションなどにおける手書き文字入力 を効率化する「音声ペン」システムについて述べる.講演者が普段通り自由に発言し電子白板に板書を行うと, システムがバックグラウンドでその音声と手書き文字を認識し,その結果に基づき次に書かれるであろう内容が 予測され,入力候補として提示される.適切な予測が得られた場合講演者はそれを選択することで文章に挿入で き,その分の手書き作業が不要となる.適切な予測が得られなかった場合,もしくは予測システムに関心がない 場合には単純に提示される予測を無視すればよく,再入力や訂正を強制されることはない点が特長である.さら に音声ペンシステムは講演者の音声認識結果を一人一人の聴衆のPCに配信し,同様の予測入力に活用すること で講演者と聴衆の間で予測入力用のコンテクスト情報を共有することができ,参加者全員の...
متن کاملWriting droplets of molecularly imprinted polymers by nano fountain pen and detecting their molecular interactions by surface-enhanced Raman scattering.
Molecularly imprinted polymer (MIP) droplets were printed using a pipet or a nano fountain pen on surface-enhanced Raman scattering (SERS)-active surfaces, to directly monitor the uptake and release of a template molecule, the beta-blocking drug propranolol, by SERS. The monitored SERS bands can be related to the template, allowing for its detection but also identification in the MIP. This is a...
متن کاملCancer-fighting fountain pen gets the job done with nanodiamonds
The probe could be used both as a research tool in the development of next-generation cancer treatments and as a nanomanufacturing tool to build the implantable drug delivery devices that will apply these treatments. The potential of nanomaterials to revolutionize drug delivery is emergent in early trials, which show their ability to moderate the release of highly toxic chemotherapy drugs and o...
متن کاملA picoliter 'fountain-pen' using co-axial dual pipettes.
A double pipette system for local, controlled drug infusion is presented. Two concentric pipettes can be manipulated separately and pressurized independently by a designated double holder. The inner pipette is loaded with the desirable solution (drug), and functions as a source, while the outer one is a sink. This gives a flow of the solution between the two pipettes that protrudes only a small...
