Dose-dependent effects of nanoscale graphene oxide on reproduction capability of mammals
TL;DR: In vivo dose-dependent effects of nanoscale graphene oxide (NGO) sheets on reproduction capability of Balb/C mice were investigated and a high graphene uptake in testis showed a high impact on sperm viability and motility.

Cyto and genotoxicities of graphene oxide and reduced graphene oxide sheets on spermatozoa
TL;DR: Physical trapping of spermatozoa by graphene (particularly GTP–rGO) is one of the important mechanisms describing the cytotoxicity, in addition to the other reactions, resulting in the inactivation and/or death of spermutozoa.

Influence of heavy nanocrystals on spermatozoa and fertility of mammals.
TL;DR: In vivo toxicity of the NCs was found lower than the in vitro toxicity, but still caused ~34% reduction in viability as well as motility and ~5% damages in DNA of male mice spermatozoa, resulting in ~26% decrease in fertility and gestation of female mice, along with an overall hormone secretion during the pregnancy.

Ugi Four-Component Assembly Process: An Efficient Approach for One-Pot Multifunctionalization of Nanographene Oxide in Water and Its Application in Lipase Immobilization
TL;DR: In this paper, the authors presented the first covalent functionalization route beginning with carboxylated-graphene oxide through Ugi four-component assembly process (Ugi 4-CAP), in which amine, aldehyde, isocyanide, and acid components come together in a one-pot reaction to generate hydrophobic-, hydrophilic-, or amiphiphilic multifunctionalized graphene composites.
