Polymers

40.6K
The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

Strategies for Assessing and Addressing Confounding

374
Confounding is a critical issue in epidemiological studies, often leading to misleading conclusions about associations between exposures and outcomes. It occurs when the relationship between the exposure and the outcome is mixed with the effects of other factors that influence the outcome. Given that, addressing confounding is of high importance for drawing accurate inferences in research.
Confounding can be addressed at both the design phase of a study and through analytical methods after data...

Conjugated Proteins02:50

Conjugated Proteins

27.6K
Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...

Protein-protein Interfaces

14.6K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Area of Science:

  • Biomaterials Science
  • Organic Electronics
  • Bioelectronics

Background:

  • Conjugated polymers offer mechanical flexibility and conductivity for bioelectronic interfaces.
  • Current in vivo applications are limited to coating inorganic electrodes, not fully organic devices.
  • A gap exists in understanding how these organic devices interact within biological systems.

Purpose of the Study:

  • To investigate the limited in vivo applications of entirely organic implantable electronic devices based on conjugated polymers.
  • To explore the reasons behind the scarcity of research on conjugated polymer-based devices in biological systems.
  • To address the limitations hindering the translation of conjugated polymers for next-generation medical implants.

Main Methods:

  • Review of existing literature on in vivo studies of conjugated polymer-based devices.
  • Analysis of factors limiting the in vivo application and translation of these materials.
  • Identification of knowledge gaps in the interface between organic electronics and biological systems.

Main Results:

  • A significant lack of comprehensive in vivo studies for fully organic conjugated polymer devices.
  • In vivo applications are predominantly confined to enhancing existing inorganic electrode performance.
  • Understanding the biological interfacing of these materials remains a critical barrier.

Conclusions:

  • The translation of conjugated polymers into fully organic implantable devices is hindered by a lack of in vivo data.
  • Further research is essential to elucidate the in vivo behavior and biocompatibility of these materials.
  • Bridging the knowledge gap is crucial for advancing flexible, next-generation medical implants.
