  1. The structure of proteins is a key factor that controls biomolecular interactions. Measuring the atomic scale structure of proteins, however, is very challenging. The most common method for determining protein structure is x-ray crystallography, but it suffers from difficult sample preparation, high sample demand and expense. Further, this method i...

  2. Magnetic field sensing has countless applications ranging from aircraft testing to detection and security applications. However, there are two major dilemmas with current sensors. First, magnetic field sensors have a low sensitivity and are unable to accurately detect failures and defects in low electrical fields. Furthermore, current sensors are o...

  3. The charged-coupled device (CCD) is commonly known for its applications in digital cameras and infrared photodetectors. Although this device has been revolutionary within imaging applications, there are some shortcomings that can be improved. For instance, a conventional CCD requires a very high external voltage. High power consumption means that p...

  4. Radiography is currently the most common medical imaging procedure performed in the world, and the demand for radiography is expected to increase in the coming years. Particularly in less developed countries where there is a demand for a much more ruggedized technology, the market may skip conventional x-ray film technology in lieu of digital radio...

  5. Spatial changes during building construction usually manifest as deviations between the as-designed model and the as-built conditions. These deviations can lead to errors that result in delays and additional costs. Project engineers often spend significant time, money, and resources to manually track and analyze changes between the as-designed mode...

  6. Electric field sensors are low cost, compact, efficient, and are able to penetrate non-conducting materials, making it a great choice for commercial application. A branch of electric field sensing known as passive electric field sensing commonly uses electric charge induction sensors called D-dot sensors. D-dot sensors analyze the voltage at specif...

  7. Obtaining a cancer diagnosis can be difficult, particularly for bladder cancer. Current bladder diagnostic strategies include either invasive cystoscopy or labor intensive urine cytology; neither of which is ideal. Different types of cells, including cancer cells, have distinct biophysical properties. Cancer cells tend to spread out and have great...

  8. Colorectal cancer is the second leading cause of cancer death in the United States and fourth worldwide. Colorectal cancer often develops from precancerous polyps, which, when found through optical colonoscopy screening, may be easily and safely removed. Unfortunately, colonoscopies are operator dependent and the quality is greatly affected by dili...

  9. Colorectal cancer is the second leading cause of cancer death in the United States and fourth worldwide. Colorectal cancer often develops from precancerous polyps which, when found early, may be easily and safely removed. Colorectal polyps are often asymptomatic and are typically detected through routine optical colonoscopy (OC) screening. While th...

  10. The bleomycins (BLMs) are well-known antineoplastic agents, clinically useful in the treatment of squamous cell carcinomas and malignant lymphomas. The carbohydrate moiety of BLM is also known to be highly tumor targeting. Methotrexate is a highly effective antitumor agent as well and is used to treat cancers of the skin, head and neck, lung and br...
