Biomaterials Plenary Session (BP)

The Biomaterials Interfaces program kicks off with the now traditional Biomaterials Plenary Session. This year we are pleased to have presentations from three eminent scientists who have made significant contributions to the field of biointerfaces. The plenary has a focus on non-fouling surfaces and honors the 70th birthday of Michael Grunze and his substantial contributions in the field of protein and adhesion resistant interfaces. In his talk he will illustrate how surface functionalization can control fundamental adhesion processes, hematocompatibility, and fouling. In particular are the correlation of fundamental physical surface parameters and quantitative biological data as well as the application and the development of spectroscopic methods for in situ and in vivo investigations of biointerfaces and cells. Morgan Alexander will describe new approaches to materials discovery for biological environments, including high-throughput approaches that integrate combinatorial materials synthesis with sophisticated, state-of-the-art surface analytical measurements. Understanding these relationships is critical in the development of the biomaterials of the future and is the theme running through his group's work across a variety of biomedical application areas spanning bacterial adhesion to controlling stem cell response. Joanna Aizenberg will talk about her substantial contributions in understanding basic principles of biological architectures and the elegance with which biology solves complex problems. She uses biological principles as guidance in developing new, bio-inspired synthetic routes and nanofabrication strategies that lead to advanced materials and devices, with broad implications in fields ranging from architecture to energy efficiency to medicine. Among recent innovations are SLIPS coatings that provide non-toxic antifouling protection of surfaces. The session will close with the opportunity for further discussions at our traditional Plenary Reception.

Novel Trends in Synchrotron and FEL-Based Analysis Focus Topic (SA)

The AVS 64 Focus Topic Novel Trends in Synchrotron & FELBased Analysis will disseminate the recent successes of scattering, spectroscopic and imaging techniques in characterization of functional materials, where the complexity of matter encompasses multiple energy, time and length-scales. The presentations are selected to present the exciting opportunities offered at the large scale synchrotron radiation and Free Electron Laser facilities for ‘seeing’ how matter evolves down to fs and to the level of nano-units, atoms and molecules. The emphasis will be on processes occurring at surfaces and interfaces where interaction-related motions involve numerous reaction and transport steps that relate directly to desirable chemical, electric and magnetic properties. The five oral sessions will cover important fields spanning over catalysis, interfacial reactions in energy devices, 2D materials, correlated systems and magnetism. In most of these systems the major challenge is to understand the origin of emergent behavior at heterointerfaces and how the interfacial structure and functionality respond to external stimuli such as temperature, electric field, light or changes in the chemical composition by exposing to various environments.

Plasma Processing for Biomedical Applications Focus Topic (PB)

Plasma processing is an ideal way to either create new or modify existing material surfaces for use in various applications, including medicine. The Focus Topic will address the most up to date challenges and latest developments of plasmas interfacing biomaterials and biological systems. This will include plasma processing of biomaterials, pharmaceuticals, and living organisms for biological, therapeutic and agricultural applications. There are two major topical categories in this Focus Topic. One is concerned with plasma synthesis or modification of biomaterials and pharmaceuticals and the other is concerned with the use of plasmas for biological applications as direct therapeutics, including treating infected tissue, wound healing, and cancer treatment, and agricultural applications for example plant growth, and sterilization. The former covers the chemistry of biomaterial surfaces and biological molecules, biointerfaces, and efficacy of medical devices that are made or modified via plasma processes. The latter covers a field known as plasma medicine, in which biological reactions in living organisms triggered by plasma generated chemically reactive species are discussed. Latest interests in these categories include plasma polymerization and surface modification to increase biocompatibility of materials, plasma processes to create antimicrobial surfaces, biomimetic materials, 3D cell scaffolds, etc., plasmaliquid interaction, plasma-enhanced chemical reactions in liquid, plasma seed and plant treatments, and plasma-cell or tissue interaction.
