ABC Transporters: Importer

ABC Transporters: Importer

ATP-binding cassette or ABC transporters are a class of ATP-driven pumps that hydrolyze ATP to move solutes across the membrane. They can be grouped into importers and exporters. While exporters are present in all domains of life, importers exist only in bacteria and some plants.
In bacteria, based on the number of transmembrane helices and the chemical nature of their substrates, the ABC importers can be divided into three types:

ABC Transporters: Exporter

ABC Transporters: Exporter

ATP-binding cassette or ABC transporter is the largest superfamily of integral membrane proteins. The transporters have transmembrane-binding domains (TMDs) and nucleotide-binding domains (NBDs). The TMDs are specific to their substrates, whereas the NBDs are similar to engines that complete ATP hydrolysis to complete the substrate transport. They can be full transporters consisting of two TMDs and NBDs, half transporters with one TMD and NBD, while some encoded with a single TMD or NBD are...

Nonconscious Mimicry

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Crossing Over

Crossing Over

Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...

Background:

ABC triblock terpolymers are key for synthesizing soft Janus nanoparticles (JNPs).
Previous JNP synthesis using these terpolymers yielded only spheres, cylinders, and sheets.
Controlling the geometry of the sandwiched microphase has been a limitation.

Purpose of the Study:

To explore continuous tuning of polybutadiene (PB) microphases in lamella morphologies.
To investigate the effect of blending polybutadiene homopolymer (hPB) into SBM triblock terpolymers.
To generate novel Janus nanostructures beyond spheres, cylinders, and sheets.

Main Methods:

Combined theoretical simulations and experimental synthesis.
Systematic variation of hPB volume fraction in polystyrene-block-polybutadiene-block-polymethylmethacrylate (SBM) terpolymers.
Morphological analysis of PB microdomains and subsequent crosslinking and redispersion.

Main Results:

Morphological transitions observed from PB-cylinders to perforated PB-lamellae and continuous PB-lamellae with increasing hPB.
Simulations confirmed homogeneous distribution of hPB within PB microdomains.
Successful generation of Janus cylinders, perforated Janus sheets, and Janus sheets.

Conclusions:

Blending homopolymers offers a versatile method for tuning microphase morphology in ABC triblock terpolymers.
This approach significantly expands the range of accessible Janus nanostructures.
Suggests potential for generating more complex Janus nanostructures than previously anticipated.
