The biological and medical fields have seen great advances in biomolecules. This review is meant to provide an overview of the various types of biosensors and biochips that have been developed for biological and medical applications, along with significant advances over the last several years in these technologies. It also attempts to describe various classification schemes that can be used for categorizing the different biosensors and provide relevant examples of these classification schemes from recent literature.
Wouldn’t it be great if you could control your PC with your brain? Well, this sort of thing may be closer than you think.
Brain-computer interfaces that can translate thoughts into actions will change how stroke patients, paraplegics and other people with limited mobility interact with their surroundings. But so far, these devices have involved bulky corded equipment inside research labs, requiring patients to be tethered to a computer. Now researchers at Brown University have built the first wireless version. Like a cellphone embedded in the brain, their new implantable brain sensor can relay broadband signals in real time from up to 100 neurons

Motivation: Radiofrequency ablation (RFA) has in recent years become a popular treatment for primary tumors in the breast, kidney, liver, and etc. However, traditional approaches of guidance such as ultrasound and computed tomography (CT) fail to provide satisfactory placement precision. Although MRI guidance offers the ability to evaluate the completeness of the RFA, those procedures that are currently done using MRI are performed under “image guidance” rather than “continuous imaging”. The goal of this research is to build a multi-DOF device for breast biopsy/RFA that is MRI compatible and teleoperated with a haptic interface. We envision a “one-sitting procedure”, whereby identification of tumor boundaries, placement of the needle, assessment of placement accuracy, ablation, and assessment of ablation accuracy can be done in one sitting, without removing the patient from the scanner or disrupting tumor location, as shown in Fig. 1.
When we talk about NASA, it’s not always the nation’s civilian space program and for aeronautics and aerospace research. Yes, the recent launch of NASA’s Curiosity Mars Rover has been phenomenal. People often argue, what has NASA actually done for us? Sending robots to other planets and controlling from Earth doesn’t give me anything. Is that what you think? (Ok. May be not). So, I came across some answers to this question and found details about the technologies and innovations that have emerged out of research and development at NASA. Here are the contributions in the healthcare field:
Scientists hope that one day in the distant future, miniature, medically-savvy computers will roam our bodies, detecting early-stage diseases and treating them on the spot by releasing a suitable drug, without any outside help. To make this vision a reality, computers must be sufficiently small to fit into body cells. Moreover, they must be able to “talk” to various cellular systems. These challenges can be best addressed by creating computers based on biological molecules such as DNA or proteins. The idea is far from outrageous; after all, biological organisms are capable of receiving and processing information, and of responding accordingly, in a way that resembles a computer.
