Significance of multi-responsive microgels for biomedical applications

There are many responsive drug-delivery systems currently available, which are based on polymers, nanoparticles, microsphere and liposome. These systems have been developed to prolong the circulation time of drug molecules in the blood so that they can be delivered to the targeted site of action while protecting them from degradation in blood plasma. Applications of hydrogels as elements of control release systems have also been well described in the literature. A further focal area of responsive drug delivery is related to the development of nanogel, which provide high surface area and rapid response to external stimuli and can therefore solve problems of hydrogels’ slow response to stimuli. Furthermore, aqueous hydrogel suspensions have been one of the most studied colloidal systems as responsive nanogels since they can manifest dramatic changes in characteristics of the system such as shape, surface characteristics, solubility, and formation of an intricate molecular self-assembly or a sol-to-gel transition.


The major aims of our current study are to prepare, characterize and evaluate stimuli responsive silver loaded poly N-isopropyl acrylamide (pNIPAAm) nano-particulate carrier systems. These DDSs have been characterised using FTIR, DSC, AA, SEM and EDEX techniques. To confirm the biological activity of silver loaded gel anti bacterial assay will be carried out using various strains of gram negative and gram positive bacteria and for confirming the physiological activity of these gels, their drug release patterns will be studied at various physiological as well as pathological temperatures. This paper will present the results of the characterization of these nano-particulate DDSs as well as their drug release behaviour in response to environmental stimuli such as temperature.

A bioabsorbable product, providing the controlled release of local anesthetics to minimize postoperative pain

Authors : E. Pélissier, C. Millot, C. Roques-Carmes, S. Piranda


This communication describes a new controlled-release substance, made of a blend of a bioabsorbable substrate and local anesthetics. The controlled-release of local anesthetics is obtained by progressive biodegradation of the substrate. The release rate can be modified depending on the compound composition and physical conditions of the making of. The amounts of local anesthetics released, are in accordance with the doses commonly used in humans by continuous wound infusion, as demonstrated by in vitro, as well as in vivo experiments on rats. The product can be either used on its own, under the form of an analgesic implant which can be placed in any type of surgical wound, or it can be applied on different sorts of medical implantable devices, to minimize postoperative pain.

Biomedical textiles in implantable medical devices

• The types of textile forming methods
• Mechanical and physical properties of textiles
• Medical devices leveraging biomedical textiles as an enabling technology
• Biomedical textile case studies
• The future of textiles in medical devices


This presentation will focus on the various methods to create biomedical textiles and the range of materials used to design in the unique physical and mechanical properties leveraged in medical devices. An overview highlights the wide range of textile structures including the order and orientation of polymeric and metallic filaments in a structure and how their distinct fabric geometries result in unique form and function capabilities to enable various design options. The versatility and variability of their properties and performance characteristics will also be discussed. Devices exist today that leverage biomedical textiles as a way of creating an effective repair of damaged or diseased tissue. Several examples will be cited. In addition, the presentation will address the potential for future medical devices that use a combination of resorbable and non-resorbable polymers, biologics and pharmaceuticals as a means of creating fibrous scaffolds and hybrid properties in a device.

Bioceramics as Drug Carriers for Controlled-Release Technology

Current practice is nowhere near ideal: drug admission and effectiveness of drug in action are not well controlled.  New controlled release technology has been heavily investigated but the market predominantly consists of polymeric materials.  However, there are certain drawbacks of polymers, such as instability of physical structure and the fact that they are not controllable at nanometre scales. This presentation will cover how these issues can be addressed with alternative drug controlled release vehicles: bioceramics.  Superior characteristics of ceramics to polymers are biocompatibility, stability and, in particular, well controlled nano structure. Potential applications for targeting and long life drugs will also be discussed in the presentation.

Hernia repair is the 2nd most practiced surgical intervention all medical disciplines confused.  The aim of the present project was the elaboration of visceral implants with a prolonged release of bioactive molecules.  The PET textile implants were functionalised with cyclodextrin (CD) acting as a host molecule, and a polycarboxylic acid used as crosslinking agent.  The mechanical and chemical properties of the textile were not altered.  The coating of PET fibres with the CD polymer was controlled by the settings of the duration and temperature applied in the thermofixation step and by the adjustment of the CD and cross-linking agent concentrations in the initial impregnating bath.
The therapeutical activation was realised by impregnation of the functionalised textile in solutions containing antibiotic or analgesic agents, which were adsorbed through inclusion complexation into the immobilized CDs cavities on the one hand, and through ionic bonding with the carboxylate residues issued from the cross-linking agent on the other hand.  The release assays and microbiological tests have shown a significantly sustained liberation of antibiotic agents and persistence of bacteriostatic/bactericidal effects on Escherichia coli (gram -) and Staphylococcus aureus (gram +).

Cost-effective nano-coating protection of medical devices (protein resistance, anti-microbial)

Modern consumer and industrial products are manufactured from a wide range of materials that are selected for specific bulk properties, cost effectiveness and/or look and feel.  However, many of the manufacturing materials chosen in this way, for sectors such as life sciences/medical devices, electronics, lifestyle, energy and filtration, do not display the optimum surface properties.  This presents a vast opportunity for surface modifications to display desirable properties such as protein resistance, anti-microbial and, water and oil repellency. It is critical that these modifications do not alter the bulk properties of the product, in order to retain desirable physical attributes. Additionally, the modification should be ultra-thin and well adhered.
A novel, patented liquid-repellent technology, by P2i, can readily apply functional nano-coatings onto the surface of a wide variety of products made from a diverse range of materials.  The liquid repellent coating is 3x more repellent than PTFE.  It optimizes the surface properties to maximise liquid repellency and, protects items to liquid ingress and reduces the potential for cross-contamination.  Overall it protects products for extended use, adding considerable value to the product in question both as a suitable differentiator and/or a cost saver. 
The process uses a pulsed plasma deposition process at low pressures and, importantly, this allows coating of complete 3D products/end devices.  This technology is fully industrialised and delivers cost-effective processes with high reliability and repeatability, ease of use and low maintenance, and the ability to operate in a range of countries and environments.  Today it is used in a number of market sectors, including medical electronic devices.


Dr. Delwyn Evans, Principal Chemist, P2i


After over four years at P2i, he is currently their Principal Chemist.  This involves developing new and innovative solutions for surface modification from concept to commercialisation.
