Electroporation is a widely used method for the introduction of polar and charged agents such as dyes, drugs, DNA, RNA, proteins, peptides, and amino acids into cells. Traditionally, electroporation is performed with large electrodes in a batch mode for treatment of a large number of cells in suspension.

The Bulletin of Mathematical Biophysics, 1967
A theory of growth of a cell which takes up nutrients by diffusion or active transport is discussed. The main conclusion is that the volume should grow at least as fast as the third power of the time. Existing experimental evidence is not a conclusive test of the theory, and further experiments to test it are proposed.

Science, 1983
Both photosynthetic and nonphotosynthetic microorganisms, grown on various carbon and energy sources, are used in fermentation processes for the production of single-cell proteins. Commercial-scale production has been limited to two algal processes, one bacterial process, and several yeast and fungal processes.

Autoradiography of Single Cells
Nature, 1947The use of radioactive isotopes or tracers in the study of fundamental biological and biochemical problems has grown enormously during the last few years, and is likely to become still more important as larger quantities of various radioactive elements are made available.

Single-cell electroporation (SCEP) is a relatively new technique that has emerged in the last decade or so for single-cell studies. When a large enough electric field is applied to a single cell, transient nano-pores form in the cell membrane allowing molecules to be transported into and out of the cell.

Single-cell biomedicine: roles of single-cell nuclear elements
Cell Biology and Toxicology, 2020Single-cell biomedicine, a new merging discipline of cell biology and medicine to improve the life quality of patients, gains high priority in cell biology and toxicology. Single-cell nuclear elements are specially focused and headlined to understand regulatory mechanisms by which transcriptional factors, DNA elements, and genome organization interact ...

The dynamics of a cell is always changing. Cells move, divide, communicate, adapt, and are always reacting to their surroundings non-synchronously. Currently, single-cell metabolomics has become the leading field in understanding the phenotypical variations between them, but sample volumes, low analyte concentrations, and validating gentle sample ...

Single‐Cell Microelectrochemistry
Angewandte Chemie International Edition, 2007AbstractNeedle‐type voltammetric ultramicroelectrodes show exceptional sensitivity for the detection of redox‐active substances, rapid response times, and total tip diameters in the lower micrometer range. These characteristics make them ideal for analyzing the chemical environment and the activity of isolated living cells, which in their various forms

Biotechnology and Genetic Engineering Reviews, 1984
This chapter describes how an industrial organization has approached the development of a single-cell protein (SCP) process, from the choice of substrate to the commissioning of the world's largest continuous fermentation plant. SCP offers a new challenge to the process engineer of fermentation at enormously increased scale.

Dr. Susan Okie discusses the controversy surrounding a recent report suggesting that new stem-cell lines may be generated while preserving embryos. On the contrary, all donated embryos used in the study were destroyed during the experiments.
