Hot paper: Bio-ink for printing living cells on demand

A bio-ink to print living cells onto a surface using a commercial printer has been developed by Dr Marc in het Panhuis and colleagues at the University of Wollongong, Australia. Bioprinting can be used for tissue engineering and analytical applications. The bio-ink consists of a gel – gellan gum – that’s used in food additives. The gel makes sure that the cells in the bio-ink remain suspended with no sign of aggregation, which was the problem with previous inks. Aggregation means an uneven distribution of cells being printed out onto a surface.

Nasal gel alternative to insulin injection: Biomaterials Science article in Chemistry World

The formulation affects the controlled delivery of insulin, demonstrated by a reduction in blood glucose over 24 hours. © Shutterstock

An international team of scientists has developed a novel insulin delivery system for nasal administration. The study aims to provide an alternative to regular injections through the delivery of insulin via the nasal membrane in the form of a hydrogel. This route offers a relatively high bioavailability, avoidance of the first-pass effect (in which a drug’s concentration is reduced before it reaches the systemic circulation) and painless administration.

Considerable research effort has been dedicated to developing alternative non-invasive insulin delivery systems, including oral and transcutaneous administration. The major limitations of nasal delivery are the rapid mucociliary clearance of a drug to the nasopharynx, resulting in a short time span for its absorption, and the low permeability of the nasal membrane to peptides such as insulin because of tight junctions between epithelial cells.

Ink containing living cells to print tissue: Biomaterials Science article in Chemistry World

Printing cellsScientists in Australia are a step closer to printing living cells for tissue engineering with the development of a new bio-ink that allows the cells to stay alive until they are printed and not clog up the printer nozzle.

‘The first bio-inks used in drop-on-demand cell printing were simple salt solutions,’ says Marc in het Panhuis, who was part of the research team at the University of Wollongong. ‘The cells in these inks settled and aggregated quickly, which impeded printing. Cell viability can also be compromised if the salt concentration is too high.’

Effects of zinc and strontium substitution in tricalcium phosphate on osteoclast differentiation and resorptionEffects of zinc and strontium substitution in tricalcium phosphate on osteoclast differentiation and resorption

Biomaterials for bone replacement must be able to regulate osteoblast and osteoclast functions to maintain the dynamics of bone remodelling. In this paper, Bose and co-workers report osteoclast-like cell differentiation and resorption activity in the presence of β-tricalcium phosphate and Zn-and Sr-doped tricalcium phosphate materials in an in vitro study. The presence of Zn was found to reduce activity in all cultures, but the osteoclast-like cellular resorption process was not affected.

A cancer treatment that goes further

A cancer treatment that uses titanium dioxide nanoparticles to kill tumour cells has been given a sound revamping by researchers in Japan. The new strategy improves the stability of the nanoparticles and the treatment may be able to penetrate more deeply into human tissues than ever before, targeting problematic tumours, through the use of ultrasound.

Atsushi Harada and colleagues at Osaka Prefecture University encapsulated the titanium dioxide nanoparticles inside micelles (an aggregate of surfactant molecules dispersed in a liquid colloid). The team grafted polyethylene glycol, a polymer with many medical uses, onto the micelles to stabilise them, improve their biocompatibility and to ensure that the micelles had negligible cytotoxicity. ‘Low cytotoxicity is the most important property of our micellar system’ Harada explains.

Profile of the Institute for Integrated Cell-Material Sciences

Now that we have published our first few articles, I thought this might be a good time to tell you a little more about the Institute for Integrated Cell-Material Sciences (WPI-iCeMS). Biomaterials Science is a collaborative venture between RSC Publishing and the iCeMS, which is based at Kyoto University, Japan.

The iCeMS is part of the Japanese government’s World Premier International Research Center (WPI) Initiative, launched in 2007 to forge a new model for scientific institutions, helping Japan lead the world in a broad range of leading-edge research. By merging materials science and cell biology, both fields of great strength at Kyoto University, the iCeMS is creating a new cross-discipline, supported by an advanced research environment and infrastructure that are unprecedented in Japan. The institute’s focus is on two main areas: stem cell science & technology and mesoscopic science & technology. The institute’s work draws from the life sciences, chemistry, materials science, as well as physics, constantly expanding the boundaries of technological innovation.

Titanium dioxide nanoparticle-entrapped polyion complex micelles generate singlet oxygen in the cells by ultrasound irradiation for sonodynamic therapy

The main cytotoxic agent in photodynamic therapy is believed to be the reactive oxygen species 1O2 which is used to treat cancerous diseases.  In this paper, Harada and co-workers investigate the generation of reactive oxygen species using sonication of TiO2 nanoparticles. They first synthesised TiO2 nanoparticle-entrapped micelles with a core-shell structure. The nanoparticles were able to generate reactive oxygen species by sonication when inside the micelles. The frequently of sonication was appropriate for clinical situations, thus they has the potential to be used in sonodynamic therapy.

A progressive approach on inactivation of bacteria using silver–titania nanoparticles

The antibacterial properties of silver compounds have long been known. In this paper by Li, Luo and Bashir, Ag-decorated TiO2 nanoparticles were prepared by a colloidal chemistry method. The nanoparticles were coincubated with model microbes, that are found in water, to investigate their biocidal effectiveness. The bactericidal mechanism was also investigated with a focus on the role of the microbial outer membrane.
