Today we will be discussing Microelectromechanical Systems, or MEMS. We will start with a brief overview of MEMS, defining what they are and briefly explaining their purpose in today’s economy. Then, we will explain the processes that manufacturers use to produce MEMS: IC Fabrication, Bulk Micromachining/Wafer Bonding, Surface Micromachining, and Micromolding. We will also discuss some of the advantages MEMS have over traditional systems, as well as some challenges and problems associated with MEMS manufacturing. Finally, we will explore potential applications of MEMS technology in the future.
Today we will be discussing Chemical Analytics through micro and nanofluidics. To start off we’ll discuss the origins of microfluidic technology and how the process of chemical analysis was moved from a costly lab process to a fast and inexpensive method than can be done in the palm of your hand. After that we’ll move onto the inner workings of the device and soft lithography, one of the methods used to create microfluidic chips. Finally we’ll leave off with some of common applications for this technology, one of the issues scientists are trying to deal with, and what the future has in store for micro and nanofluidic analytic technology.
On today’s edition of nano tech, our host Mike talks about Micro Fluidic Point-of-Care devices and interviews a local CVS representative. A POC device stands for Point-of-Care device, like a pregnancy test, that does not require the need of a laboratory or medical experience. In order to make these devices one must have the knowledge of many different fields and enough resources to cover the expense of creating them. To engineer a POC device one must know about the reaction that they are trying to make/ what they are looking for in order to design the microfluidic chip.
On today’s edition of Today in Technology, our host Bob interviews our guest, Dr. Doolittle, on her fascinating research in cancer therapy by using nanotechnology to implement new strategies, such as increased accuracy in drug delivery, which will potentially eliminate chemotherapy. Dr. Doolittle unveils why this new form of cancer therapy will be able to bypass former barriers such as biological limits or the physical disadvantages of chemotherapy. She explains how nanotechnology uses factors such as pH to target only cancerous cells and does not affect healthy cells at all, as seen in the figure below. Listen to be enlightened on the technology of the future!

This week on Additive Knowledge, we discuss several different applications of additive manufacturing. An interview with Dr. Albert Chi reveals one of the medical applications of 3D printing; child prosthetics can be made cheaply and efficiently through additive manufacturing. Afterwards, one of our journalists delivers a report on the negative consequences of additive manufacturing. The amazing precision that a 3D printer delivers, in conjunction with its ability to make objects out of plastic and metal, allows weapons to be easily fabricated by anyone who owns such a device. Listen in to gain some knowledge!

SciBridge with DJDJ and JJ Hubert brings the viewer information about how MEMs and Microfluidic systems are brought to life and where we see them everyday. Establishing this connection is extremely important because knowledge has boundaries if it has no applications. Special guest Blue Plaid from 104.9 WJRH stops by to provide his input on designed thinking in a classic example. Listen up if you want to learn where the future is headed!

Project Summary: This podcast will give a brief overview about what micromechanical surgery is, and go in depth into an application of a material studied at a micro level, and then in theory applied at a macro level. The material that we are looking at is a combination of bone and cement. This is used to benefit surgical techniques and processes in total hip replacement surgeries. This podcast includes a summary of the research study, pros and cons, and what advancements need to be made before this can be applied for consumer use.
