Abstract: Disclosed herein are cryogenic wires and methods of making and use thereof. For example, disclosed herein are cryogenic wires comprising a conductor having a mass density of 5000 kg/m3 or less; and a cladding material disposed around the conductor, the cladding material comprising a ductile and malleable metal, wherein the conductor comprises lithium, beryllium, calcium, sodium, magnesium, titanium, or a combination thereof. In some examples, the conductor comprises lithium or an alloy thereof, beryllium or an alloy thereof, calcium or an alloy thereof, sodium or an alloy thereof, magnesium or an alloy thereof, titanium or an alloy thereof, or a combination thereof.

Abstract: A colorimetric chemosensor molecule having a aza-macrocycle Zn (II)-complex (L.Zn) (Scheme 1, Formula 1A) which can recognize selectively and efficiently ATP (Adenosine triphosphate), a biologically significant triphosphate in aqueous medium at pH 7.4 is described. Since ATP is the source of energy in living organisms, L.Zn (Scheme 1, Formula 1A) can also be used as a staining agent in the living cells through binding to ATP, generated in situ during the metabolic process.
