Abstract
Optical biosensors have emerged as a powerful tool in analytical biochemistry, offering high sensitivity and specificity in the detection of various biomolecules. This article explores the advancements in the integration of optical biosensors with microfluidic technologies, creating lab-on-a-chip (LOC) platforms that enable rapid, efficient, and miniaturized analysis at the point of need. These LOC platforms leverage optical phenomena such as chemiluminescence and electrochemiluminescence to achieve real-time detection and quantification of analytes, making them ideal for applications in medical diagnostics, environmental monitoring, and food safety. Various optical detectors used for detecting chemiluminescence are reviewed, including single-point detectors such as photomultiplier tubes (PMT) and avalanche photodiodes (APD), and pixelated detectors such as charge-coupled devices (CCD) and complementary metal-oxide-semiconductor (CMOS) sensors. A significant advancement discussed in this review is the integration of optical biosensors with pixelated image sensors, particularly CMOS image sensors. These sensors provide numerous advantages over traditional single-point detectors, including high-resolution imaging, spatially resolved measurements, and the ability to simultaneously detect multiple analytes. Their compact size, low power consumption, and cost-effectiveness further enhance their suitability for portable and point-of-care diagnostic devices. In the future, the integration of machine learning algorithms with these technologies promises to enhance data analysis and interpretation, driving the development of more sophisticated, efficient, and accessible diagnostic tools for diverse applications.

Electrochemical biosensor based on functional composite nanofibers for detection of K-ras gene via multiple signal amplification strategy. Anal Biochem 2014; 466:51-8.

Abstract
An electrochemical biosensor based on functional composite nanofibers for hybridization detection of specific K-ras gene that is highly associated with colorectal cancer via multiple signal amplification strategy has been developed. The carboxylated multiwalled carbon nanotubes (MWCNTs) doped nylon 6 (PA6) composite nanofibers (MWCNTs-PA6) was prepared using electrospinning, which served as the nanosized backbone for thionine (TH) electropolymerization. The functional composite nanofibers [MWCNTs-PA6-PTH, where PTH is poly(thionine)] used as supporting scaffolds for single-stranded DNA1 (ssDNA1) immobilization can dramatically increase the amount of DNA attachment and the hybridization sensitivity. Through the hybridization reaction, a sandwich format of ssDNA1/K-ras gene/gold nanoparticle-labeled ssDNA2 (AuNPs-ssDNA2) was fabricated, and the AuNPs offered excellent electrochemical signal transduction. The signal amplification was further implemented by forming network-like thiocyanuric acid/gold nanoparticles (TA/AuNPs). A significant sensitivity enhancement was obtained; the detection limit was down to 30fM, and the discriminations were up to 54.3 and 51.9% between the K-ras gene and the one-base mismatched sequences including G/C and A/T mismatched bases, respectively. The amenability of this method to the analyses of K-ras gene from the SW480 colorectal cancer cell lysates was demonstrated. The results are basically consistent with those of the K-ras Kit (HRM: high-resolution melt). The method holds promise for the diagnosis and management of cancer.

Electrogenerated chemiluminescence aptasensor for ultrasensitive detection of thrombin incorporating an auxiliary probe. Talanta 2014; 130:370-6.

Abstract
A novel electrogenerated chemiluminescence (ECL) aptasensor for ultrasensitive detection of thrombin incorporating an auxiliary probe was designed by employing specific anti-thrombin aptamer as a capture probe and a ruthenium(II) complex-tagged reporter probe as an ECL probe and an auxiliary probe to assist the ECL probe close to the surface of the electrode. The ECL aptasensor was fabricated by self-assembling a thiolated capture probe on the surface of gold electrode and then hybridizing the ECL probe with the capture probe, and further self-assembling the auxiliary probe. When analyte thrombin was bound with the capture probe, the part of the dehybridized ECL probe was hybridized with the neighboring auxiliary probe, led to the tagged ruthenium(II) complex close to the electrode surface, resulted in great increase in the ECL intensity. The results showed that the increased ECL intensity was directly related to the logarithm of thrombin concentrations in the range from 5.0 × 10(-15)M to 5.0 × 10(-12)M with a detection limit of 2.0 × 10(-15)M. This work demonstrates that employing an auxiliary probe which exists nearby the capture probe can enhance the sensitivity of the ECL aptasensor. This promising strategy will be extended to the design of other biosensors for detection of other proteins and genes.

Abstract
The potential use of K-RAS mutation as a cancer screening biomarker has been investigated for many years. Numerous associations between K-RAS mutation and various cancers have been established, but these associations have not been translated into effective, cost-efficient cancer screening strategies. This lack of progress may be due to the existence of K-RAS mutation in nontumor tissues and/or using detection, rather than quantitation, of K-RAS mutation as the endpoint for cancer risk categorization. K-RAS mutation appears to be a useful prognostic biomarker for colon cancer. Recent progress toward sensitive and quantitative mutation characterization and the successful use of K-RAS mutation in a personalized medicine approach to targeted biological therapy selection are likely to re-direct and expand the use of K-RAS mutation as a cancer biomarker in the near future.

Abstract
A new approach was established to construct a sandwich-type electrochemiluminescence (ECL) immunosensor by using Ru(bpy)(3)(2+)-doped silica (abbreviated as Ru-SiO(2)) nanoparticles to label secondary antibody. Firstly, carboxylate-terminated multi-walled carbon nanotubes (MWCNTs) were modified on the electrode to bond with avidin. Subsequently, biotinylated antibodies were immobilized on the surface of the electrode by employing the specific interaction of biotin/avidin and the non-covalent and covalent conjugation function of MWCNTs. Later, the electrode was incubated with antigen of mouse IgG and then reacted with the secondary antibody which was labeled by Ru-SiO(2). Accordingly, through the ECL response of Ru-SiO(2) and tripropylamine (TPA), a strong ECL signal was obtained and an amplification analysis of protein interaction was achieved. The present immunosensor showed a wide linear range of 0.05-200.00 ng mL(-1) for detecting mouse IgG, with a low detection limit of 17 pg mL(-1). There was a 4-300-fold improvement in detection limit compared with other similar studies. The morphologies of Ru-SiO(2) nanoparticles were characterized by using transmission electronic microscopy (TEM). The fabrication process of the immunosensor was studied by cyclic voltammetry (CV) and the performance of the immunosensor was monitored with an electrochemiluminescence analyzer. This new strategy for preparation of the ECL immunosensor could be easily realized and has potential application in ultrasensitive bioassays.

Abstract
The identification of point mutations is particularly essential in the fields of medical diagnosis and prognosis of many pathogenic and genetic diseases. In this study, an rolling circle amplification (RCA) based electrochemiluminescence (ECL) assay for highly sensitive point mutation detection was developed. In the assay, an allele-discriminating padlock probe was designed for targeting the sequence in the p53 oncogene locus. A circular template generated by enzymatic ligation upon the recognition of a point mutation (CGT to CAT) on the oncogene could be amplified isothermally by Phi 29 DNA polymerase. The elongated products, containing hundreds of copies of the circular DNA template sequence, were hybridized with Ru(bpy)(3)(2+) (TBR)-tagged probes and then captured onto streptavidin-coated paramagnetic beads. The resulting products were analyzed by magnetic bead based ECL platform. As low as 2 amol of mutated strands was detected by this assay, which could be attributed to the high amplification efficiency of Phi 29 DNA polymerase and current magnetic bead based ECL detection platform. In addition, the positive mutation detection was achieved with a wild-type to mutant ratio of 10000:1, due to the high fidelity of DNA ligase in differentiating mismatched bases at the ligation site. It is demonstrated that this proposed method provides a highly sensitive and specific approach for point mutation detection.
