Tissue welding is a relatively new procedure that aims to seal wounds and openings in a surgery using laser. The first tissue welding application using lasers was done in 1964 to join small blood vessels ...

Optical fibers show promise not just in long-range information transmission, but also in fully optical computers. Image courtesy of tOrange.biz What is optical computing? For many decades, the processing ...

Human beings have suffered from kidney stone problems since 7000 BC. Despite advances in treatment, incidence of renal stone disorder has increased over the past few decades. Lasers have been used to ...

The first medical application of lasers was reported by Goldman in 1962. In cardiovascular surgery, McGuff first used a Ruby laser in 1963 for the experimental ablation of atherosclerotic plaques. After a ...

Since the first demonstration of the laser in 1960, people have endeavored to make lasers more compact. Semiconductor lasers achieved this desired compactness employing so called heterostructures. This ...

Laser beams are notable for their small size and long range focusing capabilities. These qualities have been used in medicine for precision surgery, and in industry for precision cutting. However, change ...

In modern medicine, the ultrasound is a go-to method for viewing the body’s internal structures, given its non-invasive nature. Ultrasound produces images in real time by relaying high frequency soundwaves ...

Previously, we discussed how visible light in combination with implantable optical sensors was used to map epileptic neural activity and localize focal seizures on the surface of the brain.  Scientists at ...

Optical technology has had a huge impact on our everyday lives. Sensational inventions like the self-driving car, Wi-Fi connected home appliances and automated assembly lines all use optical fibers or ...

A collaborative research team from Harbin Medical University and Harbin Institute of Technology present a promising alternative to detect lymphoma in blood samples in their recently published paper. The ...
