Micro-patterning is commonly done through masking. Creating a photomask involves important specifications that can directly affect a resulting pattern transfer. Mask material, environmental conditions, and type of resist should be considered. But prior to processing, photomask design characteristics must be determined.
During the photolithography process, thin film interference effects can influence a substrates surface properties. Common interference effects include the standing wave effect, reflective notching, edge bead formation, and under/over baking. The Platypus Technologies engineers have enhanced our standard operating procedures to account for potential defects caused by thin film interference effects.
Surface science is a highly complex field that spans multiple disciplines and is related to the chemical and physical interactions that take place when two phases come together. These interfaces can be solid-vacuum, liquid-gas, solid-liquid, solid-gas, etc. This article will outline some of the basic elements of surface science and how it is used.
The field of flexible electronics continues to be on the rise as technological advances continue. New materials are beginning to be utilized in fabricating electrodes for flexible electronic applications.
Microelectrodes are specially patterned electrodes with very small tip diameters (less than 1 µm) that enable in-vitro electrochemical measurements in living tissues. Other applications using microelectrodes include measuring substance concentrations and determining pH levels.
What is Material Characterization?
Material characterization enables researchers to determine the structure of a material, how this structure relates to its macroscopic properties, and how it will behave in technological applications.
Lift-off is often conducted following a series of photolithography steps that create a photoresist layer onto a substrate. Chemical and metal lift-off methods are used to create distinctive patterns onto a surface. Both types of lift-offs can be time consuming compared to wet etching, however lift-off is a safer method that offers lower production costs and enhanced processing capabilities.
Developing a new medicine and bringing it to market is a long, difficult and expensive process. This process begins with drug discovery: the unearthing of promising compounds which demonstrate some beneficial biological effect. Compound screening is the primary method by which initial drug discovery is carried out.
Spectroscopy is a broad field that comprises several different sub-disciplines and a wide array of techniques, each of which uses highly specialized equipment. This blog post explores five of the most popular types of spectroscopy.
Photolithography refers to a binary image transfer process that can be used to enhance many microfabrication applications.
Wet etching is a technique to pattern metal films into functional devices. A metal film covered with a patterned photoresist is submerged into a liquid that selectively removes exposed areas of the metal. This form of etching is an isotropic method, meaning that the metal is removed with equal rate all directions.
A research article from China Medical University investigated how a long non-coding RNA (lncRNA) known as HOTAIR contributes to the development of endometriosis.
A research study from Iowa State University explored the potential of using directional Raman scattering spectroscopy to characterize self-assembled monolayers (SAMs) deposited on gold (Au) and silver (Ag) surfaces. SAMs are formed by absorption of organic thiols (R-SH) on metal surfaces and are used in microelectronic applications requiring precise surface patterning of metal films.
Cell migration assays allow scientists and researchers to measure cell migration patterns. Platypus Technologies Oris Pro cell migration assays support many different cell types with extracellular matrix coated wells. In addition, Oris stoppers can be used to create cell free detection zones.
In a new research study from Tokyo Medical and Dental University in Japan, scientist investigated the influence of chronic inflammation on infectious phenotypes encountered with ulcerative colitis (UC), a disease of the bowels.
Gold-coated silicon wafers provide inherent electrical properties that can be used in electrochemical applications. Platypus Technologies silicon substrates are carefully engineered to serve as high-performance electrodes.
Functional metal coatings are increasingly important in research settings, enabling scientists to modulate the surface properties of different substrates to suit specific experiment parameters. Yet coated microscope slides are not a new phenomenon. Biochemists and life scientists have long exploited polymeric coatings like epoxy resin, gelatine, poly-L-lysine, and various silanes to promote better adhesion between organic samples and a substrate. Custom metal coatings are a natural progression of polymer-coated microscope slides for a more precise era of life science microscopy.
Gold-coated silicon substrates can promote molecule attachment and result in self-assembled monolayers (SAMs) in AFM, force spectroscopy, and mass spectroscopy applications. The high-purity and uniformity of gold-coated substrates provide the ideal surface for characterization methods.
New human health challenges arise in response to an array of geopolitical and socioeconomical factors including radical global population growth, paradigm shifts in social behaviour, or increased urbanization and loss of land for agriculture. This creates unique opportunities for innovators and original manufacturers (OEMs) who are willing to collaborate and deliver solutions to the next generation of environmental and human health problems.
Industries in which nanoparticles can interfere with manufacturing processes need to use a clean room to maintain the utmost accuracy. Cleanrooms control the humidity, contamination, temperature, and pressure of facilities.
