Receptor-mediated Endocytosis01:38

Receptor-mediated Endocytosis

Overview
Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...
Liver Regeneration01:24

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...
Liver Histology01:27

Liver Histology

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...
Lipid Absorption01:24

Lipid Absorption

Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...
Lipid Catabolism01:25

Lipid Catabolism

Triglycerides serve as crucial long-term energy storage molecules in microorganisms, providing a dense source of metabolic energy. Their breakdown is mediated by lipases, which hydrolyze triglycerides into glycerol and free fatty acids. Each of these components follows distinct metabolic pathways, ultimately contributing to ATP synthesis and cellular energy homeostasis.Glycerol MetabolismGlycerol, released from triglyceride hydrolysis, is phosphorylated by glycerol kinase to form...

Area of Science:

  • Condensed matter physics
  • Nanophotonics
  • Quantum mechanics

Background:

  • Light scattering in plasmonic nanoparticles is typically modeled using bulk properties and idealized boundaries.
  • Quantum effects at interfaces, due to finite electron thickness, introduce nonclassical phenomena influencing light scattering.
  • Electrical gating provides a method to control and investigate these surface effects by manipulating boundary charges.

Purpose of the Study:

  • To investigate the modulation of surface response in single plasmonic nanoresonators through direct electrical charging.
  • To analyze the impact of electrical charging on light scattering properties and understand underlying surface effects.
  • To explore the potential for electrical control over nonclassical surface phenomena in plasmonic systems.

Main Methods:

  • Single plasmonic nanoresonators were subjected to direct electrical charging via gating.
  • Changes in light scattering spectra were measured to probe alterations in the nanoresonator response.
  • Measured scattering changes were analyzed using surface response functions to distinguish classical and nonclassical effects.

Main Results:

  • Electrical charging modulated the plasmonic resonance shift, consistent with changes in the classical in-plane surface current.
  • A decrease in resonance width (reduced losses) was observed for negatively charged resonators.
  • This reduction in losses was attributed to a nonclassical out-of-plane surface response, beyond simple electron spill-out.

Conclusions:

  • Electrical gating effectively controls plasmonic light scattering by manipulating surface currents.
  • Nonclassical surface effects, particularly an out-of-plane response, significantly influence resonance width and losses.
  • These findings enable the development of electrically tunable plasmonic modulators and metasurfaces.
