“…CPCs can be classified into three types: expansion, laminar flow and mixing. The expansion type CPC was developed as a 'dust counter' and 'nephelescope' (Espy, 1841;Coulier, 1875;Aitken, 1881). The laminar flow type, comprised of a saturator, a condenser and an optical particle counter (OPC), allows for continuous monitoring.…”

The counting efficiency of an in-house laminar flow Condensation Particle Counter (CPC) was investigated experimentally. The CPC was challenged by different sources of particles (ambient particles, and combustion particles generated from CH 4 and C 2 H 4 ), and the counting efficiency of the in-house ultrafine CPC (IUCPC) was obtained by comparing particle concentration data measured by the IUCPC with that measured by a reference instrument, TSI CPC 3775. The counting efficiency is closely related to the contact angle (an indication of the wettability of particles by the working fluid) and the combination of the saturator and the condenser temperatures. The particles from different sources appeared to have different contact angles, in other words, different wettability by the working liquid.

“…As the twentieth century has progressed, it has become more and more obvious that the Olympic Games are just another yardstick of the relative economic strength of the industrialised nations, they are "forums for international competition and are utilised as tools of national foreign policy". 13 In the Olympic Games, nations competed in various classes as they had done in the international exhibitions. Here, too, the winners were awarded gold medals by impartial referees, the number of national medals totalled and the nations ranked accordingly.…”

“…There are many different real-time PCR instruments and detection probe formats available. In this review, not all different probe formats (TaqMan hydrolysis probes, molecular beacons, Scorpion probes, minor groove binding probes, and many more) [23][24][25][26] and detection principles will be explained, since detailed information about real-time PCR technology and detection formats are frequently provided in publications and reviews [27]. Some of these technologies rely on the principle of fluorescence resonance energy transfer (FRET) [28,29].…”

“…Some of these technologies rely on the principle of fluorescence resonance energy transfer (FRET) [28,29]. FRET occurs when two fluorophores are in close proximity to each other and the energy from an excited donor is transferred to an acceptor [23][24][25][26][27][28][29][30][31][32][33][34] (Fig. 1).…”

Current applications and future trends of molecular diagnostics in clinical bacteriology

Molecular diagnostics of infectious diseases, in particular, nucleic-acid-based methods, are the fastest growing field in clinical laboratory diagnostics. These applications are stepwise replacing or complementing culture-based, biochemical, and immunological assays in microbiology laboratories. The first-generation nucleic acid assays were monoparametric such as conventional tests, determining only a single parameter. Improvements and new approaches in technology now open the possibility for the development of multiparameter assays using microarrays, multiplex nucleic acid amplification techniques, or mass spectrometry, while the introduction of closed-tube systems has resulted in rapid microbial diagnostics with a subsequently reduced contamination risk. Whereas the first assays were focused on the detection and identification of microbial pathogens, these new technologies paved the way for the parallel determination of multiple antibiotic resistance determinants or to perform microbial epidemiology and surveillance on a genetic level.
