“…The available literature suggests a developmental‐dependent response of plants to various types of exogenous materials in terms of accelerating or delaying growth characteristics (Kupke et al, 2021; Ostrowska et al, 2021; Ranjan et al, 2022). Recent studies have evaluated the use of appropriate concentrations of NPs for alleviating the antagonistic effects of abiotic factors, for example, salinity and drought (Abdelsalam et al, 2023; Usman et al, 2020; Zahedi et al, 2019; Zulfiqar & Ashraf, 2021). Several types of NPs (e.g., Ag‐NPs and ZnO‐NPs) activate the antioxidant defence systems in different plant tissues, reducing ROS and improving growth (Acharya et al, 2020; Mahakham et al, 2017; Szőllősi et al, 2020; Waqas Mazhar et al, 2022).…”

Salinity and drought stress substantially decrease crop yield and superiority, directly threatening the food supply needed to meet the rising food needs of the growing total population. Nanotechnology is a step towards improving agricultural output and stress tolerance by improving the efficacy of inputs in agriculture via targeted delivery, controlled release, and enhanced solubility and adhesion while also reducing significant damage. The direct application of nanoparticles (NPs)/nanomaterials can boost the performance and effectiveness of physio‐biochemical and molecular mechanisms in plants under stress conditions, leading to advanced stress tolerance. Therefore, we presented the effects and plant responses to stress conditions, and also explored the potential of nanomaterials for improving agricultural systems, and discussed the advantages of applying NPs at various developmental stages to alleviate the negative effects of salinity and drought stress. Moreover, we feature the recent innovations in state‐of‐the‐art nanobiotechnology, specifically NP‐mediated genome editing via CRISPR/Cas system, to develop stress‐smart crops. However, further investigations are needed to unravel the role of nanobiotechnology in addressing climate change challenges in modern agricultural systems. We propose that combining nanobiotechnology, genome editing and speed breeding techniques could enable the designing of climate‐smart cultivars (particularly bred or genetically modified plant varieties) to meet the food security needs of the rising world population.

“…It is the need of the hour to get maximum yield from crop plants to feed the increasing population of the world which is expected to be more than 12 billion in 2100 [ 8 , 9 ]. To meet the growing worldwide need for food, scientists are working to reduce the negative impact of abiotic factors, increase agricultural products, advance sustainability, and ensure food security [ 10 ]. On the other hand, the physiological, biochemical, and molecular functions of plants are impaired due to salinity in a way that sustainable agriculture faces serious threats [ 11 ].…”

Salinity poses significant challenges to agricultural productivity, impacting crops’ growth, morphology and biochemical parameters. A pot experiment of three months was conducted between February to April 2023 in the Department of Botany, The Islamia University of Bahawalpur. Four brinjal (eggplant) varieties: ICS-BR-1351, HBR-313-D, HBR-314-E, and HBR-334-D were selected and assessed for the effects of salinity on various growth and biochemical attributes. The experiment was completely randomized in design with three replicates each. This study revealed that increased salinity significantly reduced the shoot length, root length, and leaf number across all varieties, with maximum adverse effects observed at a 300mM NaCl concentration. Among the tested varieties, ICS-BR-1351 demonstrated superior performance in most growth parameters, suggesting potential salt tolerance. Biochemically, salinity decreased chlorophyll content across all varieties, with the sharpest decline observed at the highest salt concentration. V4 (HBR-334-D) showed a 57% decrease in chlorophyll followed by V3 (HBR-314-E) at 56%, V2 (HBR-313-D) at 54%, and V1 (ICS-BR-1351) at 33% decrease at maximum salt levels as compared to control. Conversely, carotenoid content increased up to -42.11% in V3 followed by V2 at -81.48%, V4 at -94.11%, and − 233% in V1 at 300mM NaCl stress as compared to respective controls. V3 (HBR-314-E) has the maximum value for carotenoids while V1 has the lowest value for carotenoids as compared to the other three brinjal varieties. In addition to pigments, the study indicated a salinity-induced decrease in total proteins and total soluble sugar, whereas total amino acids and flavonoids increased. Total proteins showed a decrease in V2 (49.46%) followed by V3 (36.44%), V4 (53.42%), and V1 (53.79%) at maximum salt concentration as compared to plants treated with tap water only. Whereas, total soluble sugars showed a decrease of 52.07% in V3, 41.53% in V2, 19.49% in V1, and 18.99% in V4 at the highest salt level. While discussing total amino acid, plants showed a -9.64% increase in V1 as compared to V4 (-31.10%), V2 (-36.62%), and V3 (-22.61%) with high salt levels in comparison with controls. Plant flavonoid content increased in V3 (-15.61%), V2 (-19.03%), V4 (-18.27%) and V1 (-27.85%) at 300mM salt concentration. Notably, salinity elevated the content of anthocyanin, lycopene, malondialdehyde (MDA), and hydrogen peroxide (H2O2) across all varieties. Antioxidant enzymes like peroxidase, catalase, and superoxide dismutase also increased under salt stress, suggesting an adaptive response to combat oxidative damage. However, V3 (HBR-314-E) has shown an increase in anthocyanin at -80.00%, lycopene at -24.81%, MDA at -168.04%, hydrogen peroxide at -24.22%, POD at -10.71%, CAT as-36.63 and SOD as -99.14% at 300mM NaCl stress as compared to control and other varieties. The enhanced accumulation of antioxidants and other protective compounds suggests an adaptive mechanism in brinjal to combat salt-induced oxidative stress. The salt tolerance of different brinjal varieties was assessed by principal component analysis (PCA), and the order of salt tolerance was V1 (ICS-BR-1351) > V4 (HBR-334-D), > V2 (HBR-313-D) > V3 (HBR-314-E). Among the varieties studied, ICS-BR-1351 demonstrated resilience against saline conditions, potentially offering a promising candidate for saline-prone agricultural areas.

“…Nanotechnology is the science/technology to synthesize, manipulate, control and manufacture nanoparticles (NPs) having size ranging from 1 to 100 nm. 2,[8][9][10][11][12] Although efforts to employ nanotechnology to cure cancer and enhance the effectiveness of medications are still at the developmental stage, NPs have been widely used in biomedical applications. It has been reported that metal NPs, such as copper (Cu), silver (Ag) and zinc oxide (ZnO), could be potentially used to treat cancer cells without affecting normal cells.…”

The necessity to engineer sustainable nanomaterials for the environment and human health has recently increased. Due to their abundance, fast growth, easy cultivation, biocompatibility and richness of secondary metabolites, algae are valuable biological source for the green synthesis of nanoparticles (NPs). The aim of this review is to demonstrate the feasibility of using algal-based NPs for cancer treatment. Blue-green, brown, red and green micro-and macro-algae are the most commonly participating algae in the green synthesis of NPs. In this process, many algal bioactive compounds, such as proteins, carbohydrates, lipids, alkaloids, flavonoids and phenols, can catalyze the reduction of metal ions to NPs. In addition, many driving factors, including pH, temperature, duration, static conditions and substrate concentration, are involved to facilitate the green synthesis of algal-based NPs. Here, the biosynthesis, mechanisms and applications of algal-synthesized NPs in cancer therapy have been critically discussed. We also reviewed the effective role of algal synthesized NPs as anticancer treatment against human breast, colon and lung cancers and carcinoma.
