Scanning Probe Lithography: Fundamentals, Materials, and Applications

The technique of Surface Plasmon Resonance (SPL) is used to study the interaction between light and matter at the nanoscale. It provides information about the surface properties, structure, and chemical composition of materials. SPL can be used to measure the thickness of films, the density of particles, and the binding strength of molecules. It also has applications in biosensing, drug delivery, and energy harvesting.

Finally, we will summarize the strengths, limitations, and potential of SPL.

Historical Background:

SPL has its roots in the early 1980s, when researchers began exploring the use of lasers for patterning surfaces. Initially, the technique was limited to the production of simple patterns, such as lines and dots. However, with the advancement of laser technology and the development of new materials, SPL has become a versatile tool for fabricating complex devices and structures.

Mechanism of Sample Modification/Manipulation:

The mechanism of SPL involves the use of a laser to create patterns on a surface. The laser beam is focused on the surface using an optical microscope, and the patterns are created by varying the intensity, duration, and wavelength of the laser beam. The patterns can be created in a variety of ways, including photolithography, electron beam lithography, and maskless lithography.

Types of AFM Tips:

AFM tips are essential components of SPL, as they are used to scan the surface of the sample and create the patterns. There are several types of AFM tips available, including cantilevers, needles, and spheres. Cantilevers are the most common type of AFM tip, as they are used to scan the surface of the sample. Needles are used to create small patterns, while spheres are used to create large patterns.

Technical Parts of the Experimental Setup:

The experimental setup for SPL involves several technical parts, including a laser, an optical microscope, an AFM tip, and a sample holder. The laser is used to create the patterns on the surface of the sample, while the optical microscope is used to focus the laser beam on the surface. The AFM tip is used to scan the surface of the sample and create the patterns. The sample holder is used to hold the sample in place during the scanning process.

Materials on Which the Technique Can Be Applied:

SPL can be applied to a wide range of materials, including metals, polymers, and ceramics. The choice of material depends on the desired properties of the fabricated device or structure. For example, metals are commonly used for electronic devices, while polymers are used for medical implants.

Different Types of Devices and Structures Fabricated by SPL:

SPL has been used to fabricate a wide range of devices and structures, including microelectromechanical systems (MEMS), microfluidic devices, and optical devices. MEMS devices are small devices that are integrated into larger systems, such as smartphones and tablets. Microfluidic devices are devices that are used to manipulate small amounts of fluids, while optical devices are devices that are used to detect and manipulate light.

Processing Steps:

The processing steps involved in SPL include the preparation of the sample, the creation of the patterns on the surface of the sample, and the fabrication of the devices and structures. The preparation of the sample involves cleaning the surface of the sample and removing any contaminants. The creation of the patterns on the surface of the sample involves using a laser to create the patterns. The fabrication of the devices and structures involves using a variety of techniques, such as etching, deposition, and lithography.

Examples and Different Approaches:

There are several examples and different approaches to SPL, performed by different international research groups. For example, one research group used SPL to fabricate a microfluidic device that was used to detect and manipulate cells. Another research group used SPL to fabricate a MEMS device that was used to measure the temperature of a liquid.
