“…This experiment utilizes two processes reported previously in the literature, microcontact printing of polymer grids (1) and metallization of the polymer grid (2). 12 The previous paper described the creation of a conductive micro/nanoscale grids using a molecular template, with no subsequent electroanalytical or chemical analysis. 12 Although these processes have been reported previously, this experiment is novel because, to date, there have been no reports in this Journal or elsewhere describing assessment of the electrochemical behavior of a metallized, molecular template printed using soft lithography.…”

“…After the cleaning procedure, residual moisture was driven from the glass substrates and PDMS stamps by placing them on a hot plate and moderately heating for 10 min prior to the experiment as reported previously. 12 Before printing the PVP grid, glass substrates were covered with two pieces of smooth, transparent tape, leaving a 2 mm gap for printing the grid on bare glass (Figure 3). This allowed the creation of a narrow grid (Figure 4) rather that a grid covering the entire glass substrate.…”

This paper describes a laboratory exercise used to address the ongoing need for nanotechnology-related, hands-on laboratory experiences for undergraduate students. Determination of the electrochemical behavior of student-fabricated silver nanogrids is reported. Students successfully used cyclic voltammetry to analyze silver nanogrids printed using microcontact printing and subsequent metallization. The silver nanogrids exhibit electrochemical behavior similar to that of electrodes manufactured in industry. Additionally, optical microscopy, atomic force microscopy, and scanning electron microscopy were used to assess nanogrid quality and dimensions.

A new experiment for use in introductory nanotechnology courses is described. This experiment allows students to fabricate metallic wires with microscale lateral dimensions and nanoscale vertical dimensions. Fabrication occurs in the capillaries of polydimethylsiloxane (PDMS) stamps modified with hydrophilic polymers. This experiment provides students with an opportunity to conduct templateassisted electrodeposition of micro-and nanomaterials, utilizing a reusable template instead of the commonly used porous, anodic alumina oxide (AAO) membranes that require dissolution to examine the wires. Fabrication of the metal wires is accomplished via the reduction of metal cations in the channels of modified PDMS stamps. In addition, this experiment introduces students to characterization using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and atomic-force microscopy (AFM). The microscale dimensions of the silver wires accommodate imaging with optical microscopy for institutions possessing limited characterization capabilities.

“…Scanning probe microscopy (SPM) has increasingly become integrated in undergraduate laboratories and research activities. − However, it can be challenging to find very small samples for SPM studies to provide an interesting “hands-on” experience with nanoscience. We have found that undergraduates can easily prepare nanostructures of organosilanes on surfaces using lab protocols based on particle lithography to demonstrate chemistry reactions at the nanoscale.…”

Preparation of Octadecyltrichlorosilane Nanopatterns Using Particle Lithography: An Atomic Force Microscopy Laboratory

2017

View full text Add to dashboard Cite

Experiments are described that involve undergraduates learning concepts of nanoscience and chemistry. Students prepare nanopatterns of organosilane films using protocols of particle lithography. A few basic techniques are needed to prepare samples, such as centrifuging, mixing, heating, and drying. Students obtain hands-on skills with nanoscale imaging using an atomic force microscope (AFM) when they learn to characterize samples. Designed surfaces are made using a surface mask of latex or silica spheres to generate nanopatterns of organosilanes. An organic thin film is applied to the substrate using steps of either heated vapor deposition or immersion in solution. The steps for preparing samples are not complicated; however, the nanostructures that are produced by particle lithography are exquisitely regular in geometry and surface arrangement. At the molecular level, two types of sample morphology can be made depending on the step for depositing organosilanes. Ring-shaped nanostructures are produced with heated vapor deposition through a particle mask, and nanoholes are produced within a matrix film using immersion of masked substrates. Experience with advanced AFM instrumentation is obtained for data acquisition, digital image processing, and analysis. Skills with chemical analysis are gained with bench methods of sample preparation. Concepts such as the organization of molecules on surfaces and molecular self-assembly are demonstrated with the visualization of nanopatterns prepared by students. Experiments with particle lithography can be used as a laboratory module or for undergraduate research projects, and are suitable for students with a multidisciplinary science background.
