Nanotechnology Now - Press Release: Smart wound dressings open up new perspectives in patient care

Home > Press > Smart wound dressings open up new perspectives in patient care

Continuous and localized monitoring of wound healing with biosensors

Abstract:
Biosensors are capable of measuring the healing process of wounds. Their integration in wound dressing materials or other medical textiles opens up new and cost-effective perspectives in patient care. In a European project directed by the CSEM Centre Suisse d'Electronique et de Microtechnique SA (CSEM), intensive research is being conducted in this area. The sixth NanoEurope, which will be held in St.Gallen (Switzerland) on September 16 and 17, 2008, will present this application and other innovations from the field of nanotechnology to the interested specialist public.

Smart wound dressings open up new perspectives in patient care

St.Gallen, Switzerland | Posted on July 4th, 2008

A biosensor uses biological parameters to detect changes in its environment. In brief, it converts a biological response into an electrical signal. A number of biosensors are available in the market-place today, for example the glucose biosensor for determining the level of sugar in the blood of diabetics. Research efforts are now focusing on biosensors which can be integrated in wound dressing materials and other medical textiles, which will monitor the wound healing process.

Safer, simpler, more cost-effective
Sensors capable of measuring the health condition of patients on the basis of certain criteria allow continuous monitoring of the healing process. Any irregularities are detected at an early stage. Applied to ambulatory healthcare, convalescent persons, or patients with chronic diseases, this method of monitoring reduces costs and increases the safety and comfort of the people affected.

CSEM in Neuchâtel heads the European "Biotex" project, whose goal is to develop wearable bio-sensors for measuring wound healing. The biosensor is integrated in the wound dressing and tests two quantities: the pH value indicating the acidity of the wound, and the CRP protein measuring the degree of inflammation. This enables the status of wound healing to be checked and acute inflam-mations to be detected at an early stage. Alarm signals are triggered quickly without requiring the removal of the dressing from the wound, which greatly reduces the risk of infections.

Remote wound monitoring offers large benefits not only for skin grafts or ulcer treatments, but generally allows more exact and comprehensive ambulatory monitoring. These developments are now being extended to other fields, such as for assisting people in extreme situations, for instance fire-fighters.

About NanoEurope 2008
NanoEurope: Platform for innovations in nanotechnology
At the specialist conference on "Multifunctional Textiles" that will be held in St.Gallen on September 16, 2008, Stéphanie Pasche from CSEM will present the state of research in the field of wearable biosensors to the interested specialist public. This specialist conference is part of the sixth NanoEurope, the European specialist congress with exhibition for technology and know-how transfer in nanotechnology.

Information for visitors and for exhibitors is provided at www.nanoeurope.com.

At a glance: NanoEurope 2008
Date: September 16 – 17, 2008
Venue: Olma Messen St.Gallen, St.Gallen, Switzerland
Exhibition: Hall 9.1, Congress: Halls 9.1.2, 9.2, and 2.1.
Registration: Via OnlineTicket at www.nanoeurope.com

After the successful event last year, which some 3,500 visitors from over 40 countries attended, the NanoEurope will once again this year offer a meeting platform for the interested specialist public. The 2008 event offers entrepreneurs and managers from industry and research institutions a forum for discussing commercialization strategies and providing investment know-how for man-agers. In addition, attendees will learn more about the following principal subjects: Multifunctional Textiles, Nano-based Electronic and Sensor Systems, and Systems with Functionalized Surfaces and Structures. Finally, for the fourth time now, the internationally renowned “NanoRegulation Conference” on voluntary measures in Nano Risk Governance including an international Nano Stakeholder Dialog will be organized as part of the NanoEurope 2008.
