The preparation method is reasonable in technique, simple in preparation and strong in operability, thus being easy to realize industrializedproduction.

Multimode microalgae culture equipment
PendingCN111996103AImprove lighting effectsFull lightBioreactor/fermenter combinationsBiological substance pretreatmentsEngineeringCulture mediums
The invention belongs to the field of microalgae culture, and discloses multimode microalgae culture equipment. The multimode microalgae culture equipment comprises an outer box assembly and a plurality of culture units, wherein the outer box assembly comprises an outer box, an air pump, fluorescent tubes and a plurality of sample bottles, and the culture units are in one-to-one correspondence tothe sample bottles; each culture unit comprises culture tanks and pressure densimeters; the air pump is used for pumping air into the outer box from outside; the fluorescent tubes are arranged in theouter box; the sample bottles are arranged outside the outer box; each culture tank is provided with a microalgae injection port and a culture medium injection port; and each pressure densimeter is provided with two pressure detection pieces located at different heights, and is used for detecting the real-time density of a microalgae solution through the real-time pressure difference detected by the two pressure detection pieces. Therefore, culture of the microalgae in three manners by the equipment can be completed, and data acquisition is performed, and subsequent sample contrast and analysis are performed.

Bioactive Glass Nanoparticles Physiological Environment Stability Modification Method and Biomedical Application
ActiveCN109513009BGood biocompatibilityGood biological stabilityOrganic active ingredientsInorganic non-active ingredientsCancer cellBioactive glass
The invention relates to a method for modifying the physiological environmental stability of biological active glass nanoparticles and biomedical application. The method comprises the steps of dissolving a modifying agent into deionized water or buffer liquid, mildly stirring until the hydrophilic modifying agent containing phosphate is dissolved, adding the biological active glass nanoparticles to generate modification, and carrying out centrifugal washing and freeze-drying, so as to obtain a product. The modification technique is simple, feasible and mild in reaction condition; the biological active glass nanoparticles are modified by virtue of the ion action force among anionic groups such as calcium ions and phosphate radicals in the modifying agent and the absorption effect of the biological active glass nanoparticles to rich proteins in serum for the first time, so that the hydrophily and stability of the biological active glass nanoparticles in different dispersion systems are improved, and the modified biological active glass nanoparticles have good physiological environmental stability, are capable of effectively inhibiting the growth and proliferation of cancer cells andhave huge utilization potentialities in the biomedical fields such as the restoration and reconstruction of tissues and the treatment of cancers.
