Abstract
We developed a handheld fluorescence detection system for capillary-based enzyme-linked immunosorbent assay (ELISA). The detection system implements both a long-pass filter and perpendicular optical arrangement, i.e., a power LED and a palm-sized spectrometer, to minimize background signals from the excitation light and optical scattering. The lower detection limit for resorufin was 0.13 μM. The detection system was applied to the quantification of C-reactive protein (CRP) in human serum with a capillary-based ELISA. The lower detection limit for CRP was 31 ng/ml, and the observed CRP levels in human serum were comparable to those obtained with a conventional ELISA system.

Abstract
The preparation of a glass capillary pattered with lipid layers on which lactate dehydrogenase (LDH) and glucose dehydrogenase (GDH) were regionally adsorbed and its application for simultaneous detection of d-glucose and l-lactate in human serum is described. A lipid layer was formed on the surface of BSA-unabsorbed octadecyltrichlorosilane (OTS) inner wall of a glass capillary. The electrostatic charge of the lipid layer was a key factor for adsorbing the enzymes on the lipid layer. The fluorescence intensities were observed at each enzyme site in the presence of diaphorase (DIA), β-nicotinamide-adenine dinucleotide oxidized (NAD), resazurin, d-glucose and l-lactate. The fluorescence intensities at each enzyme site increased with an increase in the concentration of d-glucose and l-lactate=with the detection limits of 32 μM and 4.9 μM, respectively.

Abstract
The development of label-free optical biosensors for DNA and other biomolecules has the potential to impact life sciences as well as screening in medical and environmental applications. In this report, we developed a localized surface plasmon resonance (LSPR) based label-free optical biosensor based on a gold-capped nanoparticle layer substrate immobilized with peptide nucleic acids (PNAs). PNA probe was designed to recognize the target DNA related to tumor necrosis factor. The nanoparticle layer was formed on a gold-deposited glass substrate by the surface modified silica nanoparticles using silane-coupling reagent. The optical properties of gold-capped nanoparticle layer substrate were characterized through monitoring the changes in the absorbance strength, as the thickness of the biomolecular layer increased with hybridization. The detection of PNA-DNA hybridization with target oligonucleotides and PCR-amplified real samples were performed with a limit of detection value of 0.677 pM target DNA. Selective discrimination against a single-base mismatch was also achieved. Our LSPR-based biosensor with the gold-capped nanoparticle layer substrate is applicable to the design of biosensors for monitoring of the interaction of other biomolecules, such as proteins, whole cells, or receptors with a massively parallel detection capability in a highly miniaturized package.
