What is the Materials Today Virtual Conference: Biomaterials?

While at one point materials science may have been synonymous with metals, alloys, glasses, composites, and polymers; there can be no denying that the softer and smaller materials now play a critical role. Just as with nanomaterials, the field of biomaterials exploded onto the scene during the first few years of the previous decade, continuing to grow rapidly year-on-year.

At the interface between the life sciences and physical sciences, biomaterials is at the forefront of 21st century research; including topics such as regenerative medicine, tissue engineering, implantable devices, drug delivery systems, and DNA manipulation.

Materials Today is delighted to invite you to take part in our next free, online-only event, covering all aspects of biomaterials. Just complete the form below to take part.

Invited presenters

Bioresorbable electronics
John A. Rogers, University of Illinois at Urbana-Champaign

A characteristic feature of modern silicon integrated circuit technology is its ability to operate in a stable, reliable fashion, almost indefinitely for practical purposes. Recent work demonstrates that carefully selected sets of materials and device designs enable a class of silicon electronics that have the opposite behavior -- it physically disappears in water or biofluids, in a controlled manner, at programmed times. This talk summarizes recent work on this type of ‘transient’ electronics technology, ranging from basic studies of dissolution of the key materials, to development of components and systems with radio frequency operation, to invention of schemes for externally ‘triggering’ transient behavior. Emphasis is on bioresorbable forms of such devices, for use in non-antibiotic bacteriocides and other applications of relevance to clinical healthcare.

Biocomposites and devices with naturally derived polysaccharides
Marco Rolandi, University of Washington

The ability to precisely assemble biological and bioinspired molecules into organized structures has contributed to significant advances in bionanotechnology. These advances include materials, structures, and devices that interface with biological systems. Here, I will present three such examples with chitin nanofibers and derivatives. The first example is chitin nanofiber ink — a solution of squid pen β-chitin that self-assembles into ultrafine α-chitin nanofibers upon drying. The second example is chitin nanofiber ink fabrication — chitin nanofiber micro- and nanostructures made with airbrushing, replica molding, and microcontact printing. The third example is bioprotonics — complementary field effect transistors with proton-conducting chitin derivatives containing acid and base functional groups.

Atomic layer deposition for medical and biological applications
Roger Narayan, University of North Carolina and North Carolina State University

Over the past four decades, atomic layer deposition has been successfully utilized for the growth of thin films of many classes of materials, including metal oxides, metals, polymers, and inorganic-organic hybrid materials. This talk will review the use of atomic layer deposition for growth of conformal thin films on medical device materials and biologically-derived materials. In particular, recent advances involving the use of atomic layer deposition for the development of biosensors, drug delivery devices, and implants will be considered. The commercialization of atomic layer deposition technology for medical applications will also be discussed.

DNA architectures for materials engineering
Jennifer N. Cha, University of Colorado, Boulder

While nanomaterials have shown great potential for electronic and photonic applications, it has been difficult to organize them onto surfaces for incorporation into functional devices. To address some of these challenges, we have focused on assembling nanoscale materials on surfaces with control over material location and crystallographic orientation. The first part of this talk will highlight our recent efforts in directing and patterning single-stranded DNA and DNA templates on substrates with micro- and nanoscale resolution. A number of different substrates were patterned by optical and e-beam lithography to create highly parallel arrays of meso- and macroscale DNA “origami” scaffolds. Using DNA templates encoded with multiple nanometer recognition sites, hierarchical assemblies were generated consisting of both organic and inorganic nanoscale materials. The latter half of the talk will highlight our current research efforts in developing high yielding chemistries to attach DNA to surface and biomaterials for biosensing applications and also the use of DNA to create switchable nanoparticle based probes.

Platforms for engineering functional three-dimensional tissues
Suwan Jayasinghe, University College London

The ability to manipulate and distribute living mammalian cells with control presents fascinating possibilities for a plethora of applications in healthcare. These range from possibilities in tissue engineering and regenerative biology/medicine, to those of a therapeutic nature. The physical sciences are increasingly playing a pivotal role in this endeavor by both advancing existing cell engineering technology and pioneering new protocols for the creation of biologically viable structures. The presentation will briefly introduce leading technologies, which have been fully validated from a physical, chemical and biological stand point for completely demonstrating their inertness for directly handling the most intricate advanced material known to humankind. A few selected biotechnological applications will be presented where these protocols could undergo focused exploration.
