Implementation of sodium alginate-Fe3O4 to localize undiagnosed small pulmonary nodules for surgical management in a preclinical rabbit model

Scientific Reports, 2022
Many methods are used to locate preoperative small pulmonary nodules. However, deficiencies of complications and success rates exist. We introduce a novel magnetic gel for small pulmonary nodules localization in rabbit model, and furtherly evaluate its ...

Magnetorheology of Magnetic Composite Gels

NIPPON GOMU KYOKAISHI, 2009
Softmaterials containing magnetic particles demonstrate the change in rheological properties upon magnetic field, this is called the magnetorheology. A variety of magnetorheological materials has been investigated for the past decade. The magnetic effect on the rheological properties strongly depends on not only the types of matrix but also magnetic ...
