Magnetically Controlled Reversible Photomagnetic Nanoactuators for Dynamic Contrast Enhancement in Optical Coherence Tomography

open access: yesAdvanced Materials, EarlyView.
Photomagnetic nanoactuators with ≈90% scattering efficiency in the second near‐infrared window are demonstrated to exhibit magnetic field‐controlled modulation of optical scattering and optical coherence tomography signals. These nanoactuators are reversibly assembled and disassembled under the external magnetic field modulation, enabling enhanced ...

Ultra‐Fine 3D Bioprinting of Dynamic Hyaluronic Acid Hydrogel for in Vitro Modeling

open access: yesAdvanced Materials, EarlyView.
3D bioprinting merges tissue engineering and additive manufacturing to create biological structures. A bioink is developed by modifying hyaluronic acid, a natural extracellular matrix polymer, with cysteine. Potassium iodide is later added to tune gelation kinetics, enabling fine printing with a 32G needle.

Looking at the unborn: historical aspects of obstetric ultrasound [PDF]

open access: yes, 2000
The obstetric ultrasound scanner had its major origins in a programme of research undertaken in Glasgow in the 1950s and 1960s, under the leadership of the obstetrician, Professor Ian Donald.

Engineering Cellular Self‐Adhesions Inside 3D Printed Micro‐Arches to Enhance Cell:Biomaterial Attachment

open access: yesAdvanced Materials, EarlyView.
Surprisingly, a cell can bind to itself to make a self‐adhesion, which engineered here to improve how cells attach to biomaterials. Nanoprinting are used to make 3D structures smaller than cells–called Self‐Adhesion‐Tunnels (SATs)–around which cells can wrap and bind to themselves.

Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance

open access: yesAdvanced Materials, EarlyView.
This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

Bioactive Glass Microscaffolds Fabricated by Two‐Photon Lithography

open access: yesAdvanced Materials, EarlyView.
Microstructuring of bioactive glasses offers great potential to influence cell behavior for bone tissue engineering. By utilizing two‐photon lithography of a nanocomposite and thermal post‐processing, single‐micron features and complex structures are achieved.
