🚀 Spotlight: Enhancing Orthopedic Implants with Laser-assisted Surface Alloying shared by Prof. David Bahr🚀 I'm thrilled to share a groundbreaking publication from the Journal of Materials Chemistry B by Sotoudeh Sedaghat, Akshay Krishnakumar, vidhya Selvamani, Ph.D, James P Barnard, Sina Nejati, Haiyan Wang, David A. Detwiler, Mohamed N. Seleem, and Rahim Rahimi. 🔬 Title: Laser-assisted surface alloying of titanium with silver to enhance antibacterial and bone-cell mineralization properties of orthopedic implants Their innovative approach uses silver nanoparticle (AgNP) coating followed by selective laser-assisted surface alloying on titanium alumina vanadium (TiAl6V4) implants, yielding remarkable results: ✅ Enhanced Antibacterial Properties: Effective against Staphylococcus aureus and Escherichia coli. ✅ Improved Osteointegration: Twofold increase in bone mineralization. ✅ Maintained Mechanical Integrity: Minimal change in bulk mechanical properties. This technique promises to improve the longevity and effectiveness of orthopaedic implants, addressing critical challenges such as infection and implant failure. 📖 Read the full article: Laser-assisted surface alloying of titanium with silver to enhance antibacterial and bone-cell mineralization properties of orthopedic implants, Link:https://lnkd.in/grgan9Rs. #OrthopedicImplants #BiomedicalEngineering #LaserSurfaceModification #Nanotechnology #MaterialsScience #Research #Innovation #Antibacterial #Osteointegration #RSCPublishing Feel free to connect and discuss potential collaborations or applications of this technology! 🌟

PDF Bioactive Glasses. Materials, Properties and Applications H.O. Ylänen (Eds.) digsell https://lnkd.in/d4x-zBJZ Due to their biocompatibility and bioactivity, bioactive glasses are used as highly effective implant materials throughout the human body to replace or repair damaged tissue. As a result, they have been in continuous use since shortly after their invention in the late 1960s and are the subject of extensive research worldwide. Bioactive glasses provides readers with a detailed review of the current status of this unique material, its properties, technologies and applications. Chapters in part one deal with the materials and mechanical properties of bioactive glass, examining topics such as surface modification and cell interaction. Part two is focussed on … Read More » https://lnkd.in/dw7hKxdb

In this new study, authors' main objective was to compare rotational and lateral PIS, assessed in terms of IT and ISQ values, thus, achieved with tapered and parallel bone-level implants of the same coronal diameter and length. To learn more read the full study here: https://lnkd.in/dtY2RcU2

📶 Using the fat layer tissue of the body to transmit data to a #prosthesis? 🤨 So, for example, we want to move a prosthetic arm with the help of an implant: the brain signal will be transmitted throughout our body fat, up to the prosthesis able to receive it 🤯 ? It is indeed possible! 💡 Subdermal fat layer was even demonstrated as one of the best transmission biological medium for #microwaves signals, and constitutes to the development of Fat-intrabody Communication (Fat-IBC). We explain you shortly how it works and how we use this technique in our B-CRATOS project. ⤵ Thanks to Dr. Robin Augustine Kachiramattom, Bappaditya Mandal (Uppsala University), Rossella Gaffoglio (LINKS Foundation) for the insights! #fatIBC #BCI #technology #innovation

🏥 Revolutionizing Healthcare with FAT-IBC Technology At Probingon, we're proud to message the pivotal role of the B-CRATOS project in advancing healthcare through our groundbreaking technology - FAT-IBC. 🚀 It will be a: 🌟 Game-Changer for Medicine and Healthcare FAT-IBC (Fat Intra-Body Communication) is not just another innovation; it's a game-changer! This technology harnesses the body's adipose tissue as a data highway, enabling wireless and implantable medical devices like pacemakers, glucose sensors, and drug delivery systems. 📡 💡 Personalized and Preventive Medicine FAT-IBC goes beyond conventional healthcare solutions. It empowers personalized and preventive medicine by monitoring patients' health status in real-time and continuously. This means quicker, more effective responses to health issues, improving patient outcomes and quality of life. 💪 Shaping the Future of Healthcare With FAT-IBC, we're shaping the future of medicine and healthcare. This technology brings us one step closer to a healthcare system that's not just reactive but proactive. #BCRATOS #FATIntraBodyCommunication #HealthcareInnovation #PersonalizedMedicine #PreventiveHealthcare #probingon_ab

My latest research effort has been published on Elsevier Materials Today Bio!

Patent of the Day 💡 DeviceMed has published an update on their website in which they feature a 'patent of the day'. Guess which patent!! Our team developed the ceramic hermetic packaging for our Brain Interchange System. Protecting the fine electronics is of high importance, at the same time the implant and thus also the hermetic encapsulation must be able to cope with resistance. In other words, the implant must be safe for the patient. This is only one of many features we have developed to build our closed-loop system for the treatment of neurological diseases.
