Using Photolithography to Pattern Metal Surfaces

Share this post:

Many life sciences applications benefit from photolithography, a method of microfabricating materials, because of its low-cost, efficient process. A substrate is covered with a photoresist and exposed to light to remove specific areas, leaving a patterned image behind. This blog post will look at why photolithography is used to pattern metal surfaces and the benefits it provides.

How Photolithography Factors into Semiconductor Manufacturing

Share this post:

Photolithography is the pioneering technique used to generate functional patterns on various substrates. Precision microfabrication often occurs at scales and levels of throughput that conventional machining paradigms cannot achieve. No mechanical tools can etch microelectronics for complex devices like integrated circuits, optical components, and bio-sensors. Photolithography, meanwhile, is perfectly suited to the task. 

Critical Benefits of Cell Invasion Assays

Share this post:

Cell-based assays are crucial for analyzing cell health, cytotoxicity, invasion, migration,  and many other biological and drug-discovery applications and cancer research. A cell invasion assay is one of many different types of assays. It measures cell movement across extracellular boundaries and how single cells respond to various chemo-attractants. This blog post will provide an overview of the critical benefits of cell invasion assays. 

Why use a Custom Metal Coating?

Share this post:

A custom metal coating can be created from electron beam vapour deposition on different substrates. Various systems are available for metal deposition, but the highest purity custom metal coatings are achieved via e-beam deposition. An electron beam is the best way to achieve a thin film coating to protect your surfaces.

How Thin Films Factor into Surface Science

Share this post:

Thin films are used in a wide range of advanced applications in surface science, and studies surrounding thin films have significantly advanced solid state chemistry and physics. Surface science relates to any surfaces, interfaces and their applications and any research or development in the field. Thin films play a large part in surface science, and this blog post aims to cover how and why.

Applications Of Wound Healing Assays

Share this post:

Wound healing assays measure cell migration over a two-dimensional (2D) monolayer. As cell migration takes place throughout numerous physiological processes, it has been studied in a variety of contexts from tissue injury, wound healing, cancer metastasis and more. Throughout the following post, we will explain the applications of wound healing assays and the importance of each.

What is the Difference Between Invasion and Cell Migration Assays?

Share this post:

Many biomedical research projects revolve around analysis of the cell. Information about cell types, cell proliferation, cell count, and cell migration is critical to advancing disease treatment and health studies. To extract this knowledge, scientists rely on various types of assays that focus on characterizing a specific property or function of target cell types. This blog post will provide a brief overview of the difference between invasion and cell migration assays, with an emphasis on cell migration assays from Platypus Technologies.

What is a Disk Electrode Used For?

Disk electrodes are one of the essential components for performing many electrochemical experiments. Measurements such as cyclic voltammetry are widely used methods for the characterization of nearly any material or process that involves electron transfer – something ubiquitous in any material or component that will be used as part of an electronic system.

Advantages and Disadvantages of Photolithography

Share this post:

Photolithography, also known as optical lithography, is a microfabrication technique that uses light to produce precisely patterned thin films over substrates such as silicon wafers. These patterned films typically protect selected areas of the underlying substrate during subsequent processing, such as etching or metal deposition.

Why Is There a Shortage of Silicon Chips?

Share this post:

Silicon chips are a type of integrated circuit that is the primary electronic component of computing devices. The chips are mainly made from silicon (as the name suggests), which is the second most abundant element on the earth. In the last few years, there has been a significant shortage of silicon chips across the world. In this article, we explain the reasons why and the effects of this shortage.

The Evolution of Cell Culture Surfaces

Share this post:

Cell culture surfaces are surfaces on which cells are grown under controlled conditions away from their natural environment. The cells under investigation are isolated from the tissue and are sustained and preserved under carefully controlled conditions. 

The History of Cell Culture Surfaces

In the past century, cell culture, growth, and differentiation have moved from fringe experiments to a widely used bioproduction tool. In this time, the cell culture surfaces themselves have evolved as the research requirements adjust. 

How are Silicon Wafers Used in Electrochemistry

Share this post:

Silicon wafers are materials that are used for the production of semiconductors. They can be found in many types of electronic devices that are used in everyday life. Silicon wafers are super-flat disks that are refined into a mirror-like surface, they are extremely clean and free from impurities and micro-particles.

Silicon wafers are particularly well suited to use in electronic devices because electrical currents can pass through silicon conductors than many other materials. Here we will explore more about the uses of silicon wafers in electrochemistry and some of their key characteristics.

What are the Steps in Cell Migration

Share this post:

Cell migration is an extremely important cellular process. It is the directed movement of a group of cells or a single cell when responding to chemical and mechanical signals. This fundamental process takes place throughout life and continues until death, contributing to pathogenic states in disease. This article will outline the key steps of the process and how they work.

Using Photolithography for Surface Patterning

What is Photolithography?

Photolithography, sometimes known as optical lithography or UV lithography is a process that is used in microfabrication for surface patterning parts of a thin film or the bulk of a substrate. Photolithography uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical photoresist or simply resist on the substrate.
