Reservoir computing is an unconventional computing paradigm that uses system complexity and dynamics as computational medium. Currently it is the leading computational paradigm in the fields of unconventional in materia computing. This review briefly outlines the theory behind the term ‘reservoir computing’, presents the basis for evaluation of reservoirs and presents a cultural reference of reservoir computing in haiku. The summary highlights recent advances in physical reservoir computing and points out the importance of the drive, usually neglected in physical implementations of reservoir computing. However, drive signals may further simplify the training of reservoirs’ readout layer training, thus contributing to improved performance of reservoir computer performance.

“…[10] In contrast to conventional electrochemical techniques, due to the separation of excitation signal and output signal, PEC assay possesses low background signal, which reduces the background interference. [11] PEC analytical methods have gained widespread application in detecting various targets, such as bacteria, proteins, nucleic acids, small molecules, and metal ions. [12] Importantly, the efficacy of PEC methods critically hinges upon the semiconductor materials for the photoelectrode, and an array of photoactive semiconductor materials has been developed for PEC sensors, including metal oxide (TiO 2 , ZnO), [13] metal sulfides compound (Bi 2 S 3 , Ag 2 S) [14] and nanocomposite materials (AuNRs@TiO 2 , Bi 2 S 3 /TiO 2 ).…”

Detecting CO2 in complex gas mixtures is challenging due to the presence of competitive gases in ambient atmosphere. Photoelectrochemical (PEC) techniques offer a solution, but material selection and specificity remain limiting. Here, we invented a hydrogen‐bonded organic framework material based on a porphyrin tecton decorated with diaminotriazine (DAT) moieties. The DAT moieties on the porphyrin molecules not only facilitate the formation of complementary hydrogen‐bonds between the tectons but also function as recognition sites in the resulting porous HOF materials for the selective CO2 adsorption. In addition, the in‐plane growth of FDU‐HOF‐2 into anisotropic molecular sheets with large areas of up to 23,000 μm2 and controllable thickness between 0.298 and 2.407 µm were realized by a simple solution‐processing method in over 89% yields. The FDU‐HOF‐2 can be directly grown and deposited onto different substrates including silica, carbon, and metal‐oxides by self‐assembly in situ in formic acid. As a proof of concept, a screen‐printing electrode deposited with FDU‐HOF‐2 was fabricate as a label‐free photoelectrochemical (PEC) sensor for CO2 detection. Such a signal‐off PEC sensor exhibits low detection limit for CO2 (2.3 ppm), reusability (at least 30 cycles), and long‐term working stability (at least 30 days).

“…In the PEC process, the electron donor can consume photogenerated holes to prevent the recombination of electron–hole pairs and generate anodic photocurrent when the valence band (VB) position of the photoactive material is lower than the VB position of the electron donor. − In contrast, the conduction band (CB) position being higher than that of the electron acceptor can facilitate the reduction reaction to produce a cathodic photocurrent. − Overall, the generation of cathodic/anodic photocurrent requires a well-matched energy level between the photoelectrode material and the electron donor/acceptor. − Therefore, the addition of an electron donor/acceptor with a suitable energy band in the electrolyte can promote photocurrent enhancement. For example, Zhao et al enhanced the anodic PEC performance of the MnO 2 @Co 3 O heterostructure by using ascorbic acid (AA) as an electron donor to consume the produced holes .…”

Photocurrent polarity reversal is a switching process between the anodic and cathodic pathways and is critical for eliminating false positivity and improving detection sensitivity in photoelectrochemical (PEC) sensing. In this study, we construct a PEC sensor with excellent photocurrent polarity reversal induced by ascorbic acid (AA) as an electron donor with the energy level matching the photoactive material zirconium metal−organic framework (ZrMOF). The ZrMOF-modified electrode demonstrates cathodic photocurrent in the presence of O 2 as an electron acceptor, while the anodic photocurrent is generated in the presence of AA, achieving photocurrent polarity reversal. By the in situ release of AA from AA-encapsulated apoferritin modified with DNA 2 (AA@APO-S2) as a detection tag in the presence of trypsin after the recognition of hairpin DNA-modified indium tin oxide to the reaction product of aptamer/DNA 1 with the target protein and the following rolling cycle amplification for introducing the detection tag to the sensing interface, the reversed photocurrent shows an enhanced photocurrent response to the target protein, leading to a highly sensitive PEC sensing strategy. This strategy realizes the detection of vascular endothelial growth factor 165 with good specificity, a wide linear range, and a low detection limit down to 5.3 fM. The actual sample analysis offers the detection results of the proposed PEC sensor comparable to those of commercial enzyme-linked immunosorbent assay tests, indicating the promising application of the photocurrent polarity reversal-based PEC sensing strategy in biomolecule detection and clinical diagnosis.
