Abstract
Fluorescence polarization (FP) has been applied in detecting chemicals and biomolecules for early-stage diagnosis, food safety analyses, and environmental monitoring. Compared to organic dyes, inorganic nanomaterials such as quantum dots have special fluorescence properties that can enhance the photostability of FP-based biosensing. In addition, nanomaterials, such as metallic nanoparticles, can be used as signal amplifiers to increase fluorescence polarization. In this review paper, different types of nanomaterials used in in FP-based biosensors have been reviewed. The role of each type of nanomaterial, acting as a fluorescent element and/or the signal amplifier, has been discussed. In addition, the advantages of FP-based biosensing systems have been discussed and compared with other fluorescence-based techniques. The integration of nanomaterials and FP techniques allows biosensors to quickly detect analytes in a sensitive and cost-effective manner and positively impact a variety of different fields including early-stage diagnoses.

Abstract
Effective signal enhancement for fluorescence anisotropy in a simple manner is most desirable for fluorescence anisotropy method development. This work aimed to provide insights into the fluorescence anisotropy of terminally labeled double-stranded DNA (dsDNA) to facilitate a facile and universal design strategy for DNA recognition based applications. We demonstrated that fluorescence anisotropy of dsDNA could be regulated by the nature of dyes, the molecular volume, and the end structure of dsDNA. Fluorescence anisotropy ascended with the increased number of base pairs up to 18 bp and leveled off thereafter, indicating the molecular volume was not the only factor responsible for fluorescence anisotropy. By choosing dyes with the positively charged center, high fluorescence anisotropy signal was obtained due to the confinement of the segmental motion of dyes through the electrostatic interaction. By properly designing the end structure of dsDNA, fluorescence anisotropy could be further improved by enlarging the effective overall rotational volume, as supported by two-dimensional (2D) (1)H-(1)H nuclear Overhauser enhancement spectroscopy (NOESY). With the successful enhancement of the fluorescence anisotropy for terminally labeled dsDNA, simple and universal designs were demonstrated by sensing of major classes of analytes from macromolecules (DNA and protein) to small molecules (cocaine).

Abstract
Here, we combine T7 exonuclease (T7 Exo) signal amplification and polystyrene nanoparticle (PS NP) amplification to develop novel fluorescence polarization (FP) aptasensors. The binding of a target/open aptamer hairpin complex or a target/single-stranded aptamer complex to dye-labeled DNA bound to PS NPs, or the self-assembly of two aptamer subunits (one of them labeled with a dye) into a target/aptamer complex on PS NPs leads to the cyclic T7 Exo-catalyzed digestion of the dye-labeled DNA or the dye-labeled aptamer subunit. This results in a substantial decrease in the FP value for the amplified sensing process. Our newly developed aptasensors exhibit a sensitivity five orders of magnitude higher than that of traditional homogeneous aptasensors and a high specificity for the target molecules. These distinct advantages of our proposed assay protocol make it a generic platform for the design of amplified aptasensors for ultrasensitive detection of various target molecules.

Abstract
In this work, two different configurations for novel amplified fluorescence polarization (FP) aptasensors based on nicking enzyme signal amplification (NESA) and graphene oxide (GO) enhancement have been developed for ultrasensitive and selective detection of biomolecules in homogeneous solution. One approach involves the aptamer-target binding induced the stable hybridization between an aptamer probe and a fluorophore-labeled DNA probe linked to GO, and forms a nicking site-containing duplex DNA region due to the enhancement of base stacking. The second analytical method involves the target induced the assembly of two aptamer subunits into an aptamer-target complex, and then hybridizes with a fluorophore-labeled DNA probe linked to GO, forming a nicking site-containing duplex DNA region. The formation of the duplex DNA region in both methods triggers the NESA process, resulting in the release of many short DNA fragments carrying the fluorophore from GO, generating a significant decrease of the FP value that provides the readout signal for the amplified sensing process. By using the NESA coupled GO enhancement path, the sensitivity of the developed aptasensors can be significantly improved by four orders of magnitude over traditional aptamer-based homogeneous assays. Moreover, these aptasensors also exhibit high specificity for target molecules, which are capable of detecting target molecule in biological samples. Considering these qualities, the proposed FP aptasensors based NESA and GO enhancement can be expected to provide an ultrasensitive platform for amplified analysis of target molecules.

Abstract
Fluorescence anisotropy (FA) is a reliable, sensitive, and robust assay approach for determination of many biological targets. However, it is generally not applicable for the assay of small molecules because their molecular masses are relatively too small to produce observable FA value changes. To address this issue, we report herein the development of a FA signal amplification strategy by employing graphene oxide (GO) as the signal amplifier. Because of the extraordinarily larger volume of GO, the fluorophore exhibits very high polarization when bound to GO. Conversely, low polarization is observed when the fluorophore is dissociated from the GO. As proof-of-principle, the approach was applied to FA detection of adenosine triphosphate (ATP) with a fluorescent aptamer. The aptamer exhibits very high polarization when bound to GO, while the FA is greatly reduced when the aptamer complexes with ATP, which exhibits a maximum signal change of 0.316 and a low detection limit of 100 nM ATP in buffer solution. Successful application of this strategy has been demonstrated that it can be constructed either in a "signal-off" or in a "signal-on" detection scheme. Moreover, because FA is less affected by environmental interferences, FA measurements could be conveniently used to directly detect as low as 1.0 μM adenosine triphosphate (ATP) in human serum. The universality of the approach could be achieved to detect an array of biological analytes when complemented with the use of functional DNA structures.

Abstract
Fluorescence anisotropy (FA) is a reliable and excellent choice for fluorescence sensing. One of the key factors influencing the FA value for any molecule is the molar mass of the molecule being measured. As a result, the FA method with functional nucleic acid aptamers has been limited to macromolecules such as proteins and is generally not applicable for the analysis of small molecules because their molecular masses are relatively too small to produce observable FA value changes. We report here a molecular mass amplifying strategy to construct anisotropy aptamer probes for small molecules. The probe is designed in such a way that only when a target molecule binds to the probe does it activate its binding ability to an anisotropy amplifier (a high molecular mass molecule such as protein), thus significantly increasing the molecular mass and FA value of the probe/target complex. Specifically, a mass amplifying probe (MAP) consists of a targeting aptamer domain against a target molecule and molecular mass amplifying aptamer domain for the amplifier protein. The probe is initially rendered inactive by a small blocking strand partially complementary to both target aptamer and amplifier protein aptamer so that the mass amplifying aptamer domain would not bind to the amplifier protein unless the probe has been activated by the target. In this way, we prepared two probes that constitute a target (ATP and cocaine respectively) aptamer, a thrombin (as the mass amplifier) aptamer, and a fluorophore. Both probes worked well against their corresponding small molecule targets, and the detection limits for ATP and cocaine were 0.5 μM and 0.8 μM, respectively. More importantly, because FA is less affected by environmental interferences, ATP in cell media and cocaine in urine were directly detected without any tedious sample pretreatment. Our results established that our molecular mass amplifying strategy can be used to design aptamer probes for rapid, sensitive, and selective detection of small molecules by means of FA in complex biological samples.

Abstract
A colorimetric, non-cross-linking aggregation-based gold-nanoparticle (AuNP) probe has been developed for the detection of DNA and the analysis of single-nucleotide polymorphism (SNP). The probe acts by modulating the enzyme activity of thrombin relative to fibrinogen. A thrombin-binding aptamer with a 29-base-long oligonucleotide (TBA(29)) assembled on the nanoparticles (TBA(29)-AuNPs) through sandwich DNA hybridization was found to possess ultra-high anticoagulant potency. The enzyme inhibition of thrombin was determined by thrombin-induced aggregation of fibrinogen-functionalized 56 nm AuNPs (Fib-AuNPs). The potency of the inhibition of TBA(29)-AuNPs relative to thrombin--and thus the degree of aggregation of the Fib-AuNPs--is highly dependent on the concentration of perfectly matched DNA (DNA(pm)). Under optimal conditions [Tris-HCl (20 mM, pH 7.4), KCl (5 mM), MgCl(2) (1 mM), CaCl(2) (1 mM), NaCl (150 mM), thrombin (10 pM), and TBA(29)-AuNPs (20 pM)], the new TBA(29)-AuNP/Fib-AuNP probe shows linear sensitivity to DNA(pm) in the concentration range 20-500 pM with a correlation coefficient of 0.96. The limit of detection for DNA(pm) was experimentally determined to be 12 pM, based on a signal-to-noise ratio (S/N) of 3. The new probe was successfully applied to the analysis of an SNP that is responsible for sickle cell anemia. Relative to conventional molecular-beacon-based probes, the new probe offers the advantages of higher sensitivity and selectivity towards DNA and lower cost, showing its great potential for practical studies of SNPs.

Abstract
Based on the aptamer-conjugated core-shell near-infrared fluorescent nanoparticles (NIR-Nps) and fluorescence anisotropy measurement, the present study reported proof-of-principle for a rapid homogeneous assay approach that can detect target cancer cells without the need of the complicated separation steps in whole blood samples. Experimental investigation showed that the novel NIR-Nps have negligible background fluorescence and low inner filtration interference in complex biologic systems such as whole blood. The specific recognition characteristic of aptamer in whole blood samples was investigated by using the proposed fluorescence anisotropy method. The results showed that the fluorescent nanoparticle-tagged aptamer probes sequence could achieve specific recognition of the target cancer cells from complex mixtures including whole blood samples. And the reaction conditions for the binding between fluorescent nanoparticle-conjugated aptamer probes and target cancer cells were optimized. The present approach can exhibit sensitive and reproducible fluorescence anisotropy responses to the target cells concentration and the calibration curve showed good linearity when the target cells concentration is in the range from 4.0 x 10(3) to 7.0 x 10(5)cells/mL. Moreover, the present fluorescence anisotropy assay technique could be practically utilized for the detection of acute leukemia samples with improved capabilities and be comparable to the immunophenotyping methods clinically used.

Abstract
In the last decade, the field of nanoparticle (NP) technology has attracted immense interest in bioimaging and biosensing research. This technology has demonstrated its capability in obtaining sensitive data in a noninvasive manner, promising a breakthrough in early-stage cancer diagnosis, stem cell tracking, drug delivery, pathogen detection and gene delivery in the near future. However, successful and wide application of this technology relies greatly on robust NP engineering and synthesis methodologies. The NP development steps involve design, synthesis, surface modification and bioconjugation. Each of these steps is critical in determining the overall performance of NPs. It is desirable to obtain NPs that are highly sensitive, stable, imageable, biocompatible and targetable. It is also desirable to obtain multimodal/multifunctional NPs that will enable imaging/sensing of the target using multiple imaging/sensing modalities. In this review, we focus on silica NPs that have been developed for biosensing applications and silica-based multimodal/multifunctional NPs for bioimaging applications.
