We propose an antibody-based specific recognition-induced neighbor-joining reaction that initiates the assembly of two molecularly designed nucleic acid enzymes (MNAzymes), to release an oligonucleotide that hydrolyzes TWJ through the mechanism of a toehold-mediated strand displacement reaction (TSDR). Subsequently, a hybridization chain reaction application (HRCA)-based dendrimer is formed, which immobilizes a large number of quantum dots to generate a burst effect that reduces the photocurrent signal.

Tigernut is a potential source of valuable edible oil; however, current oil extraction techniques are inefficient. We assessed high temperature-induced variations in oil absorption and enzymatic hydrolysis of tigernut starch (TS) in the presence of protein to explore the intrinsic reasons for the low oil extraction from tigernut. The results showed that, due to high temperature and the presence of protein, an increase in the volume mean diameters and agglomeration of TS granules occurred.

MDT significantly reduced the crystallinity and double helix structures of the starch, without altering its native A-type crystal structure. After microwaving for 140 s and 180 s, the extraction yield of TS was significantly increased from 14.

The results showed that the introduction of MW-AE treatment prior to Ene-AE enhanced enzyme accessibility, resulting in MW + Ene-AE achieving the highest efficiency for polyphenol extraction from seeds, with a 67 % improvement compared to the control sample. Different treatments significantly altered the composition of polyphenols in the seeds, with a noticeable conversion of polyphenol glycosides to aglycones observed in Ene-AE and MW + Ene-AE.
