(ECL) is chemiluminescence that is triggered by electrochemical techniques, and it has received broad applications because of its advantages, such as high sensitivity and wide dynamic range. In recent years, some novel luminescent nanomaterials have been developed and widely used to fabricate ECL biosensors with the development of nanoscience and nanotechnology. This Review presents a general description of luminescent nanomaterials as ECL emitters from the last five years, including semiconductor quantum dots (QDs), carbon-based materials, metal nanoclusters (NCs), and upconversion nanoparticles (UCNPs). The basic mechanisms, developments, and applications of these materials are given. Finally, we conclude with a brief look at the future challenges and prospects in the development of ECL sensors.

“…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.
