Integrated luminescent chemical microsensors based on GaN LEDs for security applications using smartphones

Development of PCB-integrateable microsensors for monitoring chemical species is a goal in areas such as lab-on-a-chip analytical devices, diagnostics medicine and electronics for hand-held instruments where the device size is a major issue. Cellular phones have pervaded the world inhabitants and their usefulness has dramatically increased with the introduction of smartphones due to a combination of amazing processing power in a confined space, geolocalization and manifold telecommunication features. Therefore, a number of physical and chemical sensors that add value to the terminal for health monitoring, personal safety (at home, at work) and, eventually, national security have started to be developed, capitalizing also on the huge number of circulating cell phones. The chemical sensor-enabled “super” smartphone provides a unique (bio)sensing platform for monitoring airborne or waterborne hazardous chemicals or microorganisms for both single user and crowdsourcing security applications. Some of the latest ones are illustrated by a few examples. Moreover, we have recently achieved for the first time (covalent) functionalization of p- and n-GaN semiconductor surfaces with tuneable luminescent indicator dyes of the Ru-polypyridyl family, as a key step in the development of innovative microsensors for smartphone applications. Chemical “sensoring” of GaN-based blue LED chips with those indicators has also been achieved by plasma treatment of their surface, and the micrometer-sized devices have been tested to monitor O2 in the gas phase to show their full functionality. Novel strategies to enhance the sensor sensitivity such as changing the length and nature of the siloxane buffer layer are discussed in this paper.

Environmental Information Access as a Security Risk

The United Sates was founded on the principles of freedom. Events in recent history have threatened the freedoms we as individuals enjoy. Notably, changes to government legislation and policies regarding access to environmentally sensitive information following September 11, 2001, are troubling. The government has struggled with a difficult balancing act. The public has the right of access to information, yet, information some view as sensitive or dangerous must be kept out of the hands of terrorists. This project examines and discusses the information access debate within the United States and how to best provide the public environmentally sensitive information.

The Europeanisation of Criminal Law and the Criminal Law Dimension of European Integration. Research Papers in Law, 3/2005

From the Introduction. In the academic year 1991-1992, Utrecht University, on my initiative, started to offer courses in European criminal law. This initiative came at a symbolic moment, just prior to the entry into force of the EU Treaty of Maastricht1 and the outlining of European policy in the areas of Justice and Home Affairs (JHA). The Director of the Legal Department, Paul DEMARET, was aware of the significance of this development and I have been given the opportunity to teach this subject at the College of Europe since 1995. Since then, JHA has evolved into one of the main areas of EU legislation. Now we are again on the threshold of an important historical feat. In June 2003, the European Convention reached agreement concerning a draft Treaty establishing a Constitution for Europe.2 The use of the term “Constitution” for the future EU Treaty is not simply cosmetic. The realisation has dawned that EU integration must be embedded in a treaty document which also regulates the rights and duties of citizens, not just with respect to European citizenship, but also with respect to, for example, Justice. Where JHA is concerned, this result acknowledges that the harmonisation of criminal law and criminal procedure and transnational cooperation cannot preclude the harmonisation of principles of due law and fair trial. Despite the substantial Europeanisation of criminal law, many criminal lawyers are defending the achievements and typicalities of their national criminal law like never before. EU initiatives are assessed from the perspective of the national agenda and national achievements. We are still too far removed from a European criminal law policy that is both European and enjoys national support. The core issue is therefore not how to keep our criminal (procedural) law national and free from European influences, but rather how to ensure democratic decision making, the quality of the constitutional state and the guarantees of criminal law in a national administrative model which has to operate increasingly interactively within a European and international context. In this contribution, the contours of the Europeanisation of criminal law are outlined and analysed. First, attention will be paid to the EC and, second, to the JHA. Following this, an evaluation and a look ahead at the current IGC are indicated.
