"Kebutuhan biomaterial akan terus meningkat, khususnya implan berbasis logam dalam aplikasi ortopedi. Implan akan berinteraksi langsung dengan jaringan tubuh dan mengalami peluruhan dalam jangka waktu tertentu. Di antara kandidat Mg dan Fe, paduan berbasis Zn merupakan salah satu biomaterial biodegradable dengan kelebihan berupa laju degradasi yang sedang dibandingkan dengan Mg dan Fe serta memiliki sifat biocompatibility yang baik. Name, paduan berbasis Zn memiliki keterbatasan dalam sifat mekanik yang inferior khususnya terkait keuletan. Penelitian ini berupaya untuk meningkatkan sifat biocompatibility paduan dan membentuk paduan berbasis Zn yang lebih unggul dalam aplikasi biomaterial. Dalam penelitian ini, diteliti pengaruh penambahan kadar Mn sebesar 0,7%, 1,2%, dan 1,5% pada paduan berbasis Zn. Metode penelitian terdiri dari pembuatan master alloy dalam proses fabrikasi sampel, pengamatan mikrostruktur paduan dengan OM, SEM, EDS, dan XRD, pengujian mekanik dengan uji kekerasan microhardness Vickers, pengujian polarisasi menggunakan larutan r-SBF yang dipreparasi sebelumnya, serta pengujian XRD sampel setelah polarisasi. Hasil analisis menunjukkan bahwa peningkatan kadar Mn mempengaruhi bentuk partikel MnZn₁₃, memperhalus ukuran butir, meningkatkan kekerasan dan sifat mekanik paduan secara keseluruhan, menurunkan laju korosi, dan mendorong terjadinya korosi yang lebih uniform.

The demand for biomaterials is expected to continue growing, particularly for metal-based implants used in orthopedic applications. Implants directly interact with the body's tissues and gradually degrade into ions within a certain period. Among potential candidates such as Mg and Fe alloys, Zn-based alloys are considered promising biodegradable biomaterials due to their moderate degradation rate and favorable biocompatibility. However, Zn-based alloys face limitations in terms of lower mechanical properties, specifically in ductility. Therefore, this research aims to enhance their biocompatibility and develop superior Zn-based alloys for biomedical applications. This study investigates the impact of incorporating different percentages of manganese (0.7%, 1.2%, and 1.5%) into Zn-based alloys. The research methodology involves casting a master alloy during the sample fabrication process, followed by microstructure observations through OM, SEM, EDS, and XRD testing. Mechanical testing is conducted using the microhardness Vickers test, while polarization testing utilizes a pre-prepared r-SBF solution followed by another XRD testing. The findings of the analysis indicate that an increase in Mn content affects the morphology of MnZn₁₃ particles, refines the grain size, enhances hardness and overall mechanical properties, reduces the corrosion rate, and promotes more uniform corrosion."

"Cell and tissue engineering” introduces the principles and new approaches in cell and tissue engineering. It includes both the fundamentals and the current trends in cell and tissue engineering, in a way useful both to a novice and an expert in the field.
The book is composed of 13 chapters all of which are written by the leading experts. It is organized to gradually assemble an insight in cell and tissue function starting form a molecular nano-level, extending to a cellular micro-level and finishing at the tissue macro-level. In specific, biological, physiological, biophysical, biochemical, medical, and engineering aspects are covered from the standpoint of the development of functional substitutes of biological tissues for potential clinical use. Topics in the area of cell engineering include cell membrane biophysics, structure and function of the cytoskeleton, cell-extracellular matrix interactions, and mechanotransduction. In the area of tissue engineering the focus is on the in vitro cultivation of functional tissue equivalents based on the integrated use of isolated cells, biomaterials, and bioreactors. The book also reviews novel techniques for cell and tissue imaging and characterization, some of which are described in detail such as atomic force microscopy"
