Axoft introduced Fleuron WISE, a new soft polymer that becomes optically invisible in water by matching its refractive index. The material is built for super-resolution imaging of biological samples, reducing the distortions that normally blur high-resolution views of water-immersed tissue. It extends the Fleuron portfolio that underpins Axoft's brain implants, where the same brain-soft material improves biocompatibility and signal stability. WISE is commercially available now. Axoft will present results at the Materials Research Society meeting in December.
