Summary
Layered double hydroxides (LDHs) show low cytotoxicity, making them promising for drug delivery. ZnAl-LDH exhibited slightly higher toxicity than MgAl-LDH, but both are safe for nanovehicle applications.
Area of Science:
- Materials Science
- Nanotechnology
- Biomedical Engineering
Background:
- Layered double hydroxides (LDHs), a class of anionic clays, are increasingly recognized for their potential as nanovehicles.
- Applications include the delivery of genes, drugs, and bioactive molecules into cells.
- The safety and potential adverse effects of LDH nanoparticles have not been thoroughly evaluated.
Purpose of the Study:
- To systematically evaluate the cytotoxicity of Layered Double Hydroxides (LDHs) with varying chemical compositions.
- To assess the effects of ZnAl-LDH and MgAl-LDH on different human cell types, including normal cells, carcinoma cells, and red blood cells.
- To determine the suitability of LDHs as safe nanocarriers for biomedical applications.
Main Methods:
- Cytotoxicity was assessed by measuring cell viability and proliferation in various human cell lines.
- Membrane damage was evaluated using specific assays.
- Hemolytic effects on red blood cells were quantified to assess potential blood compatibility.
Main Results:
- Both ZnAl-LDH and MgAl-LDH demonstrated minimal cytotoxic effects across tested cell types.
- ZnAl-LDH showed a slightly higher degree of membrane damage and hemolysis induction compared to MgAl-LDH.
- No significant adverse effects were observed, indicating a favorable safety profile for both LDH types.
Conclusions:
- Layered double hydroxides (LDHs) exhibit a low cytotoxicity profile, supporting their use in biomedical applications.
- ZnAl-LDH and MgAl-LDH are identified as potentially safe and effective nanocarriers for drug and gene delivery.
- Further research into LDH-based nanovehicles is warranted, considering their promising biocompatibility for novel inorganic drug delivery systems.

01:00Cellular Injury I: Introduction
Cellular injury occurs when a cell cannot maintain homeostasis or adapt to stressors such as hypoxia, toxins, or trauma. Depending on severity and duration, injury may be reversible, allowing recovery, or irreversible, leading to cell death.General Mechanisms of Cell InjuryAlthough causes vary, most cellular injuries arise from a few key mechanisms that disrupt essential functions and often amplify one another. Cell survival depends on the extent and balance of these disturbances.ATP depletion...
01:24Drug Toxicity: Dose-Dependent Reactions
Drug toxicities can be stratified into pharmacological, pathological, or genotoxic based on their mechanisms. The incidence and severity of these toxicities generally increase with the drug's concentration in the body and exposure time.Pharmacological toxicity is evident when the therapeutic effects of drugs overshoot into adverse reactions in a predictable, dose-dependent manner. Central nervous system (CNS) depression from barbiturates is a classic example, with effects escalating from...
04:01Factors Affecting Solubility
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:
01:26Toxic Reactions: Overview
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

01:25Bioactivation and Tissue Toxicity
Bioactivation is a metabolic process that transforms less reactive substances into highly reactive metabolites, initiating tissue toxicity. This transformation can lead to various toxic effects, including carcinogenesis and teratogenesis. Reactive metabolites are classified into two main types: electrophiles and free radicals.Electrophiles are electron-deficient species and are produced primarily by the enzyme cytochrome P-450 during the metabolism of compounds containing carbon, nitrogen, or...
01:16Cellular Injury IV: Necrosis
Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
