22.10.2019Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a delicate 3D framework. This is achieved using additive 3D printing methods - so called "bioprinting" techniques. However, some methods are very imprecise or only allow a very short time window in which the cells can be processed without being damaged.
18.10.2019The ability of cataract surgery to restore sight is well known. People say they're stunned by the vibrancy of color after surgery and the improvement in night vision. Some can even reduce their reliance on glasses. But is it possible to quantify that improved quality of vision?
25.09.2019Nanolaser has potential to treat neurological disorders or sense disease biomarkers. Researchers have developed a tiny nanolaser that can function inside of living tissues without harming them. Just 50 to 150 nanometers thick, the laser is about 1/1,000th the thickness of a single human hair.
18.09.2019Cancer treatment could be dramatically improved by an invention at the University of Waterloo to precisely locate the edges of tumors during surgery to remove them.
17.09.2019The Optical Research Group of the Universitat Jaume I has developed an optical nanoparticle sensor capable of detecting very low glucose concentrations, such as those present in a person's tear, by means of fluorescent carbon quantum dots, applying synthesis of nanomaterials based on irradiation with ultra-short lasers, which is an alternative, sustainable and non-polluting method.
22.03.2019Over six million people in Germany have diabetes. It is estimated that almost 400 million people are affected by this disease worldwide. Diabetes sufferers must prick their fingers several times a day to monitor their blood sugar.
01.09.2017Many people are affected by heart disease today because - among other reasons- our modern unhealthy lifestyle is taking a toll on our hearts. A reliable diagnosis and treatment are crucial for patients with heart disease since all other organs depend on the pumping of our vital organ. Modern imaging techniques are a key to understanding the heart.
03.07.2017Precision work is absolutely essential in eye surgery since the surgical site is very minute and sensitive. This is why eye surgeons have been using lasers for years. Femtosecond lasers are especially well suited to serve this purpose because they are able to cut tissue with great precision and little energy, which prevents unwanted side effects of surgery.
03.07.2017Not all lasers are the same – especially in the surgical field, it all depends on what’s inside: the different operational wavelengths of laser light also affect human tissue in different ways. This is why a single laser for a variety of applications drastically simplifies the job of physicians.
03.07.2017The scalpel is considered the classic surgical instrument and as such, has remained unchanged for quite some time. However, today’s technology opens up a world of new possibilities for cutting tissue. Next to high-frequency electrosurgical scalpels that work with electric power, surgeons also use a variety of different lasers. They promise great usability and better treatment.
03.07.2017Advanced bile duct tumors cannot always be removed surgically. Then, patients receive chemotherapy and a stent that corrects the narrowing of the bile duct that is caused by the tumor. Another, local therapy option is tested at the University Hospital Frankfurt: laser light is used to transport drugs into the tumor during photochemical internalization.
