Fluorescent logic systems for sensing and molecular computation: structure–activity relationships in edge-detection

Abstract

Molecular logic-based computation continues to throw up new applications in sensing and switching, the newest of which is the edge detection of objects. The scope of this phenomenon is mapped out by the use of structure-activity relationships, where several structures of the molecules and of the objects are examined. The different angles and curvatures of the objects are followed with good-fidelity in the 10 visualized edges, even when the objects are in reverse video.

Consolidating Molecular Logic with New Solid‐Bound YES and PASS 1 Gates and Their Combinations

“…Additional evidence of this consolidation can be found in a dedicated conference series; a real‐life medical application; a number of dedicated books and reviews; and sections of other books and reviews; and several dedicated special issues and article collections, such as this one . Other evidence includes the extension of Boolean principles to molecular versions of arithmetic, ID tagging, cryptography, arrayed logic, in situ imaging, conditional photodynamic therapy, intracellular logic, multi‐valued logic and human‐level computing . Extending the principles learned with molecules in solution to those on solids would be one general avenue of this consolidation scenario.…”

Population analysis to increase the robustness of molecular computational identification and its extension into the near-infrared for substantial numbers of small objects

“…Molecular logic-based computation1–10 is a field where molecules perform Boolean and related operations usually belonging to semiconductor-based information processors. Recent developments include gate concatenation,11–13 combinatorial sensing,14,15 multi-analyte sensing,16–22 gaming,23–26 logical materials,27–31 human-level computation32–34 and cryptography 35–37. An intrinsic strength of molecular logic is that the gates are nanometric in size and therefore capable of operating in nanospaces.…”
