“…The dosage on the vegetables tends to increase, since the absorption is from both the leaves and soils. The absorbed quantities also depend on the type of plant, the soil and environmental factors, as it has been reported that 0.3 mg/L Cu 2+ released from 1000 mg/L of copper nanoparticles increases plant growth and is not toxic to the plant [87]. However, some reactions may lead to release of copper ions inside the plant cells that could be toxic.…”

“…However, they have been limitedly applied as pesticides and also support rapid plant growth. Gold nanoparticles at lower concentration in the soil have been reported to enhance the shoot to length ratio in Lactuca sativa seeds, without affecting the microbial concentration or causing any toxicity [87]. In other studies, they improved the seed germination, growth rate and yield with early flowering, high pod length, excellent chlorophyll and sugar content and enhanced free radical scavenging due to increased flavonoids content [87,97].…”

In other studies, they improved the seed germination, growth rate and yield with early flowering, high pod length, excellent chlorophyll and sugar content and enhanced free radical scavenging due to increased flavonoids content [87,97]. The mechanism of free radical scavenging follows that plants contain varied biomolecules such as flavonoids, phenolic substances, etc., and these substances by virtue of their functional groups and antioxidant properties can complex with the metallic ions in the plant and scavenge the free radicals that causes oxidative stress [60,98].…”

Nutrient deficiency in food crops is seriously affecting human health, especially those in the rural areas, and nanotechnology may become the most sustainable approach to alleviating this challenge. There are several ways of fortifying the nutrients in food such as dietary diversification, use of drugs and industrial fortification. However, the affordability and sustainability of these methods have not been completely achieved. Plants absorb nutrients from fertilizers, but most conventional fertilizers have low nutrient use and uptake efficiency. Nanofertilizers are, therefore, engineered to be target oriented and not easily lost. This review surveys the effects of the addition of macro- and nanonutrients to soil, the interaction, and the absorption capability of the plants, the environmental effect and food content of the nutrients. Most reports were obtained from recent works, and they show that plants nutrients could be enriched by applying nanoparticulate nutrients, which are easily absorbed by the plant. Although there are some toxicity issues associated with the use of nanoparticles in crop, biologically synthesized nanoparticles may be preferred for agricultural purposes. This would circumvent the concerns associated with toxicity, in addition to being pollution free. This report, therefore, offers more understanding on the application of nanotechnology in biofortification of plant nutrients and the future possibilities offered by this practice. It also highlights some of the ills associated with the introduction of nanomaterials into the soil for crop’s improvement.

“…At a global scale, the annual yield losses because of diseases and pests infestation are estimated to be between 20% and 40% [ 177 ]. To reduce the detrimental impact of pests on overall plant productivity, farmers around the world apply millions of metric tons of pesticides every year, which increases environmental pollution, ecosystem disruption, residual toxicity in food and feed, declines in soil fertility, and resistance of insect pests [ 178 ].…”

There is a need for a more innovative fertilizer approach that can increase the productivity of agricultural systems and be more environmentally friendly than synthetic fertilizers. In this article, we reviewed the recent development and potential benefits derived from the use of nanofertilizers (NFs) in modern agriculture. NFs have the potential to promote sustainable agriculture and increase overall crop productivity, mainly by increasing the nutrient use efficiency (NUE) of field and greenhouse crops. NFs can release their nutrients at a slow and steady pace, either when applied alone or in combination with synthetic or organic fertilizers. They can release their nutrients in 40–50 days, while synthetic fertilizers do the same in 4–10 days. Moreover, NFs can increase the tolerance of plants against biotic and abiotic stresses. Here, the advantages of NFs over synthetic fertilizers, as well as the different types of macro and micro NFs, are discussed in detail. Furthermore, the application of NFs in smart sustainable agriculture and the role of NFs in the mitigation of biotic and abiotic stress on plants is presented. Though NF applications may have many benefits for sustainable agriculture, there are some concerns related to the release of nanoparticles (NPs) from NFs into the environment, with the subsequent detrimental effects that this could have on both human and animal health. Future research should explore green synthesized and biosynthesized NFs, their safe use, bioavailability, and toxicity concerns.

“…Особливої уваги заслуговує вивчення впливу макро-і мікроелементів у формі цитратів на репродуктивну функцію маток, зокрема сполук Арґентуму і Купруму [6,11,12]. Застосування таких сполук характеризується високим рівнем біодоступності, що дозволяє суттєво зменшити концентрацію діючої речовини, токсичні та інші побічні впливи, тим самим забезпечити значний економічний і екологічний ефекти [4,5,7].…”

національний університет ветеринарної медицини та біотехнологій імені С.З. Ґжицького, вул. Пекарська, 50, м. Львів, 79010, Україна У роботі розглядаються окремі аспекти впливу стимулювальної підгодівлі медоносних бджіл на функціональну активність репродуктивної системи бджолиних маток. Метою досліджень було вивчення особливостей функціонування репродуктивної системи бджолиних маток за умов згодовування цитратів Арґентуму та Купруму, отриманих методом нанотехнології. Бджоли контрольної групи утримувалися за стаціонарних умов з підгодівлею цукровим сиропом (1000 мл/тиждень/бджолосім'ю). Бджоли дослідної групи за аналогічних умов отримували підгодівлю цукровим сиропом з додаванням у нього 0,5 мг Ag і 0,5 мг Cu у вигляді цитрату. Було проведено фотометрію запечатаного розплоду, гістологічне дослідження яєчників бджолиних маток, світлооптичну мікроскопію гістологічних зрізів, зважування та морфометрію 12-годинних яєць, отриманих з бджолиних чарунок. Встановлено, що інтенсивність середньодобової яйцекладки бджолиних маток дослідної групи, порівняно з контролем, зросла на 21,25 %. Виявлено збільшення середньої маси яєць дослідної групи на 1,4 %, 2,9 % та 5,9 % відповідно на ІІ, ІІІ та IV етапах досліджень порівняно з контролем. У дослідній групі спостерігалась підвищена інтенсивність трофоплазматичної активності, яка проявлялася у нарощуванні жовткової маси в ооцитах. Також у контрольній групі спостерігали розвиток апоптозу трофоцитів на ранніх стадіях оогенезу і виникнення деструктивних змін в ооцитах. Таким чином, додавання цитратів Арґентуму та Купруму впродовж 36 діб спричинило зростання інтенсивності середньодобової яйцекладки бджолиних маток у дослідній групі і кількості відкладених яєць за весь період на 17,1 % порівняно з контрольною. На фоні збільшення середньої маси яєць, отриманих від бджолиних маток дослідної групи, дані гістологічного аналізу зрізів яєчника вказують на інтенсивніший перебіг оогенезу у бджолиних маток дослідної групи порівняно з контроль ною, де спостерігалися ознаки пригнічення оогенезу.
