Overview

Professor Michael Monteiro has established an international reputation in the field of 'living' radical polymerization to create complex polymer architectures. He is now building designer polymers for various biomedical applications, including vaccines, drug delivery and stem cells. He is dedicated to translating research into commercial outcomes, with 7 PCT and provisional patents since 2005 and start-up company DendriMed Pty Ltd. He was awarded an ARC QEII Fellowship in 2004 and an ARC Future Fellowship in 2009. He has attracted ARC and NHMRC grants; and Queensland State Government funding in excess of $7 million.

International links

Professor Monteiro has built a strong collaboration with Professor Virgil Percec from the University of Pennsylvania to develop and understand the new SET-LRP. He has developed a collaboration with Professor Rachel O'Reilly from the University of Warwick to develop nanoreactors that mimic enzyme activity. In collaboration with Professor Eugenia Kumacheva from the University of Toronto, they developed temperature responsive micron-sized particles from encapsulation of cells.

Designer polymers: Synthesis of complex polymer architectures.

Professor Monteiro's research aims to develop methods of synthesising complex polymer architectures in water, with controlled particle size, molecular weight and morphology. By understanding the structure-property relations of these novel nanomaterials, targeted properties can be manufactured for vaccine and drug delivery. Easily recycled polymers that could be used in a variety of products have been synthesised.

  • Synthesis of well-defined thermoresponsive polymer structures.

    A general strategy through the use of direct azidation of alcohols allowed the sequence control of macromers via both the iterative sequential growth and iterative exponential growth methods. The chemistry was highly efficient in building polymers from a sequence of compositionally different macromers tethered together in close proximity. Using the DPPA/DBU method for near quantitative azidation of the benzyl alcohol moiety, sequence controlled polymers were made via a direct and one-step procedure for CuAAC activation. With four different macromers, spherical miktoarm star-like polymers of 50 000 molecular weight were prepared with a low dispersity, and the polymer coil size depended on the type of added macromer. Polymers made via the iterative methods opens the way for the design of advanced materials with predictable properties.

  • Water-borne nanocoating for rapid inactivation of SARS-CoV-2 and other viruses

    The rise in coronavirus variants has resulted in surges of the disease across the globe. The mutations in the spike protein on the surface of the virion membrane not only allow for greater transmission but also raise concerns about vaccine effectiveness. Preventing the spread of SARS-CoV-2, its variants, and other viruses from person to person via airborne or surface transmission requires effective inactivation of the virus. Here, we report a water-borne spray-on coating for the complete inactivation of viral particles and degradation of their RNA. Our nanoworms efficiently bind and, through subsequent large nanoscale conformational changes, rupture the viral membrane and subsequently bind and degrade its RNA. Our coating completely inactivated SARS-CoV-2 (VIC01) and an evolved SARS-CoV-2 variant of concern (B.1.1.7 (alpha)), influenza A, and a surrogate capsid pseudovirus expressing the influenza A virus attachment glycoprotein, hemagglutinin. The functional nanoworms can be easily modified to target viruses in future pandemics, and is compatible with large scale manufacturing processes.

  • Temperature-directed morphology transformation method to produce well-defined complex multifunctional polymer particles

    Producing synthetic soft worm and rod structures with multiple chemical functionalities on the surface would provide potential utility in drug delivery, nanoreactors, tissue engineering, diagnostics, rheology modifiers, enzyme mimics, and many other applications. Here, we have synthesized multifunctional worms and rods directly in water using a one-step reversible addition–fragmentation chain transfer (RAFT)-mediated dispersion polymerization at high weight fractions of polymer (>10 wt %). The chain-end functionalities included alkyne, pyridyl disulfide, dopamine, β-thiolactone, and biotin groups. These groups could further be converted or coupled with biomolecules or polymers. We further demonstrated a nanorod colorimetric system with good control over the attachment of fluorescent probes

  • Shape Control over the Polymer Molecular Weight Distribution and Influence on Rheological Properties

    The shape, breadth, and average molecular weight of the overall molecular weight distribution (MWD) largely define polymer properties. In conventional free-radical polymerization, control over this distribution is through the many competing kinetic pathways dominated by radical termination events. “Living” radical polymerization mechanistically minimizes these termination events, providing a facile route to a desired Gaussian distribution with the distribution breadth dependent upon the activity of the catalyst or modulating agent. However, producing unusually shaped distributions can only be achieved through modeling of the complex polymerization kinetics and invoking feeding and other methods. Here, we construct square, slanted, and chair-like MWDs by blending two to four polymers made using a low-reactive RAFT agent with dispersities close to 2. The blending method described here overcomes many of the difficulties in producing unusually shaped MWDs and allows control over the shape and breadth of the MWD. The concept further provides a general synthetic strategy for studying important structure–property relationships of polymers with desired processing and performance characteristics.
