Fluorescence technologies with flow cytometry have been used in the clinical sciences for many purposes since it has been established method. This is standardized for clinical analysis but also for other research based applications. It however suffers from one limitation that it is limited to 20 independent channels and is very complex to setup 20…
People in developed countries fail to realize the problems that face citizens of countries that have to fight to get pure water to drink. There have been a few technologies for that but the easiest one has been the use of a Lifestraw made by a company called Vestergaard Frandsen. The specifications are impressive: it…
LED have been used in all applications in electronics and also in imaging for providing long lasting consistent illumination, as well as indicators in instruments but only recently have started entering the market as home lights. UK based IMS Research publishes reports that estimate the market for packaged LED’s and they have estimated the market…
Keeploop has an interesting idea on combining an additional lens and LED into a compact device that is attached magnetically onto the back of the phone on top of the camera lens in a mobile phone. This increases the magnification of the phone lens and also enables to work in a macro mode. This macro-lens,…
Drug Discovery is expensive and many pharmaceutical companies make sure that the process is followed through all the steps including the ability to get their investment back from drug discovery. Janssen just got the FDA approval for tuberculosis. However, their motive was very different. There are only few hundred patients with drug resistant TB (tuberculosis)…
Ozcan’s group at UCLA has created another device called the iTube. This is an assay device that measures the concentrations of specific allergens in food. The cell phone serves as the readout interface to a very intricate biochemistry that is done with a small sample of the food. Typically, food allergen testing requires the services…
Ozcan’s group at UCLA has been innovating with mobile phones for many years before the field had developed as much as it is today. This lab had come up with fluorescent microscope on a cell phone for detection of pathogens in 2008. They also developed LUCAS which was the Lenseless Ultrawide-field Cell monitoring array which…
Need: A device that can take a picture of skin or ear that is easy to use and operate. Cellscope intends to make add-on lenses and software that will enable patients to take pictures of their ear, transmit to the doctor for quick diagnosis. The device was conceived at Dan Fletcher’s Lab in Berkeley (http://fletchlab.berkeley.edu/)…
Some things are simple just by using current technology and combining them in interesting ways. Problem statement: It is difficult to get an eye test in remote parts of the world where the doctors do not visit or cannot visit. Alternatively, an eye test requires complex instrumentation and is expensive that the Doctor even if…
David Brady of Duke University published a paper in Nature in 2012 (Brady DJ, Nature 486, 386) on 50 Gigapixel camera. The technology was interesting in that it used small camera’s that were coupled through a big lens. This may be a good strategy to make large cameras rather than depend on major lenses and…
