Design and synthesis of nucleic acid nano-environment interactome-targeting small molecule PROTACs and their anticancer activity.

Targeted protein degradation through PROteolysis TArgeting Chimeras (PROTACs) is a relatively new modality in cellular interventions. The minimum requirement for PROTACs to function is forming a tertiary complex of the protein of interest (POI), E3 ligase, and the molecular glue PROTAC. Here, we propose a new approach to modulate the nano-environment interactome of a non-protein target through a plausible quaternary complex of interactome-biomolecule of interest (BOI)-PROTAC and E3 ligase.

Cysteine-independent CRISPR-Associated Protein Labeling for Presentation and Co-delivery of Molecules Toward Genetic and Epigenetic Regulations.

Labeling of CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) associated proteins (Cas) remains an immense challenge for their genome engineering applications. To date, cysteine-mediated bioconjugation is the most efficient strategy for labeling Cas proteins. However, introducing a cysteine residue in the protein at the right place might be challenging without perturbing the enzymatic activity.

TMDC ternary alloy-based triboelectric nanogenerators with giant photo-induced enhancement.

Multifunctional self-powered energy harvesting devices have attracted significant attention for wearable, portable, IoT and healthcare devices. In this study, we report transition metal dichalcogenide (TMDC) ternary alloy (MoWS)-based self-powered photosensitive vertical triboelectric nanogenerator (TENG) devices, where the ternary alloy functions both as a triboelectric layer and as a photoabsorbing material. The scalable synthesis of the highly crystalline MoWS ternary alloy can overcome the limitations of binary TMDCs (MoS, WS) by utilizing its superior optical characteristics, enabling this semiconductor-based TENG device to simultaneously exhibit photoelectric and triboelectric properties.

Superior piezoelectric performance of chemically synthesized transition metal dichalcogenide heterostructures for self-powered flexible piezoelectric nanogenerator.

In addition to the superior electrical and optoelectronic attributes, ultrathin two-dimensional transition metal dichalcogenides (TMDCs) have evoked appreciable attention for their piezoelectric properties. In this study, we report, the piezoelectric characteristics of large area, chemically exfoliated TMDCs and their heterostructures for the first time, as verified by piezoelectric force microscopy measurements. Piezoelectric output voltage response of the MoS-WSeheterostructure piezoelectric nanogenerator (PENG) is enhanced by ∼47.
