“…Compared to QDs based optical sensors, QDs based photoelectrochemical sensors offer more advantages, such as a lower limit of detection in some fields (Yildiz et al, 2008), lower potential consumption (Khalid et al, 2011b), easier operation (electronic output without the need to purchase expensive optical equipment), and easier extension to light-addressable sensors for multichannel detection (Yue et al, 2013;Zhao et al, 2014). Because its sensing mechanism is completely different from that employed by QDs based optical sensors, normally, H 2 O 2 cannot be detected directly by QDs in photoelectrochemical systems.…”

“…There are some trends for future research in PEC aptasensing among which are: (1) Construction of new sensing interfaces based on the uses of novel photoactive materials; (2) Development of new immobilization and modification techniques that make the aptamers more easily attached to various photoactive species or label with various functional signal reporters; (3) Tailoring the aptamers/nanomaterials hybrid systems for innovative signaling strategies; (4) Manipulation of aptamers with various enzymes, e.g. polymerases, ligases, exonucleases,and endonucleases, to allow enzyme-assisted amplification.…”

“…Due to its obvious advantages and potential, substantial efforts has currently been exerted to its investigation and important advances have been achieved rapidly as evidenced by increased scholarly articles [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Many recent reviews introduced the application of different photoactive species in PEC bioanalysis, summarized the biosensing of specific biomolecules, or presented the latest developments in this field [1][2][3][4][5][24][25][26][27][28][29][30][31][32]. Readers could use the cited articles and the references therein to pursue their interest in these topics.…”

Highlights The field of photoelectrochemical (PEC) aptasensing is reviewed.  The fundamentals, signaling strategies, and the state of the art are discussed.  The future prospects of PEC aptasensing are presented. ABSTRACT Photoelectrochemical (PEC) bioanalysis represents a unique and dynamically developing methodology that offers an elegant route for sensitive biomolecular detection. Aptamers are synthetic nucleic acid molecules whose binding characteristics can rival those of protein antibodies. Originated from the fusion of PEC bioanalysis and aptamers, PEC aptasensing has rapidly becoming a subject of new research interests in recent years. Using illustrative examples, this review provides the introductory concept, bioanalysis development, signaling strategies, and the state of the art in this field. The future prospects are also discussed.

“…The electron−hole pairs that rise in the material interface are responsible for several photo-physical-chemical processes that go into the materials towards its ground and stable electronic state. Due to the increasing demand for faster and reliable bioanalysis, supramolecular compounds have been thought of as facilitators in the process to integrate new and even more sensitive and analysis and imaging techniques, in such a way that gave rise to a new sensing area, which integrates the photoelectrochemistry to bioanalysis, the photoelectrochemical (PEC) bioanalysis [74,75].…”

It is incontestable that the interactions and bonds that keep molecules united to generate unique supramolecular compounds, with individual properties, morphologies and behaviour, are of special dynamics and singular forces. Therefore, it is necessary to discuss and consider the types of interactions that may occur in a determined system, their dynamics and number, which directly act on the energetic balance that strengthen the union between participants and give rise to a supramolecule.In this chapter, a number of such supramolecular systems that find application as any component of a biosensor are presented and discussed, considering intermolecular interaction forces that confer them shape, function and unique properties. To better understand their structural dynamics and the mechanisms through which they can be used in biosensing, a brief explanation on the interaction thermodynamics, types of intermolecular interactions that compete against each other and the energetic equilibrium that originate and stabilize supramolecular systems is given. To explain how this balance of forces can be extensively exploited to develop methods to produce supramolecular compounds, an overview on supramolecular strategies is presented and their contribution is explored in each example presented in this text, to evidence the importance of planning and developing methodologies of preparation, based on
