“…In general, biosensors consist of two components: a biomolecule, which is a highly specific recognition element, and a transducer, such as an electrode [3], or an optical fiber [4], that converts the molecular recognition event into a quantifiable signal. Signal transduction has been carried out with electrochemical [5], quartz crystal microbalance (QCM) [6], optical absorption [7], fluorescence [8], surface plasmon resonance (SPR) [9], and other transducers. In these biosensors, biomolecules (ligand), such as enzymes [10], antibodies [11], oligonucleotides [12][13][14], microorganisms [15], peptides [16], cells [17] were immobilized on a solid substrate by numerous steps and used to detect the presence of an analyte, such as enzymatic substrates, antigens, oligonucleotides and so on.…”

In recent years, label-free biosensors not requiring external modifications have been receiving intense attention. A label-free optical biosensor, which retains many of the desirable features of conventional surface plasmon resonance (SPR) reflectometry, namely, the ability to monitor the kinetics of biomolecular interactions in real-time without a label has been developed with several important advantages: the biosensor device is easy to fabricate, and simple to implement, requiring only an UV-Vis spectrophotometer or flatbed scanner. Importantly, the label-free optical biosensor can be easily multiplexed to enable high-throughput monitoring of biomolecular interactions in an arraybased format. In this research, the development of a localized surface plasmon resonance (LSPR)-based label-free optical biosensor using a surface modified nanoparticle layer is aimed. This optical detection method promises to offer a massively parallel detection capability in a highly miniaturized package. The two-dimensional nanoparticle layer was formed by the surface modified silica nanoparticles. The optical properties and surface analysis of nanoparticle layer substrate were characterized through transmission measurements and atomic force microscopy (AFM). Simultaneously, the nanoparticle layer substrate was applied to the optical LSPR-based biosensor for label-free monitoring of the antigen-antibody reaction. The anti-fibrinogen antibody was immobilized onto the nanoparticle layer substrate surface. Different concentrations of fibrinogen were introduced to the anti-fibrinogen antibody immobilized nanoparticle layer substrate surface, and the change in the absorption spectrum, caused by the antigen-antibody reaction, was observed. By using this anti-fibrinogen antibody immobilized nanoparticle layer substrate; the detection limit of this optical LSPR-based biosensor was 10 ng/ml.

“…There are many published methods for determining shifts in the SP resonance. Some involve wavelength interrogation (Tian et al, 2004;Pang et al, 2007;Jory et al, 1995;Homola, 1997), whilst more recently methods which monitor the phase change of reflected light through the SP resonance have been developed (Kabashin et al, 1999;Nikitin et al, 2000;Shen et al, 1998;Wang et al, 2006;Notcovich et al, 2000;Law et al, 2007;Chen et al, 2005;Markowicz et al, 2007;Lee et al, 2008;Su et al, 2005;Wu et al, 2004;Ho and Lam, 2003;Nelson et al, 1996), though the initial work on such methods can be traced back as far as 1976 (Abelès, 1976). In this study we use a phase sensitive method, and in particular a dual-channel (two simultaneous sensing channels) system based on the differential surface plasmon ellipsometry sensing technique (Hooper and Sambles, 2004a,b;Hooper et al, 2006;Stewart et al, 2008).…”

Various types of acoustic wave devices based on surface acoustic, acousto‐optic and photoacoustic effects are increasingly used for many biomedical applications. This paper reviews the basic physical phenomena of the acoustic wave propagation and photoacoustic and acousto‐optic interactions, which determine their sensing capabilities, and discusses recent applications of these devices in biology and medicine.
