and how the said compound s are released is also critical for achieving the maximum effect to address this matter a novel approach combined with the disclosed micro container is illustrated in fig1 as shown in fig1 a bio compatible capping material 141 can be used to seal the narrow opening of the said micro container following a desired compound 511 or compounds being filled into the container the bio compatible capping material 141 is selected such that it can dissolve in the environment along its way to the target or in the environment surrounding the target in a desired time frame resulting in the timed release of compound s in the targeted area as shown in fig1 for example it can dissolve in human blood or an acid environment in the stomach all which can be manipulated depending on the desired therapeutic outcome the timing is such that the narrow opening is opened in a desired time frame upon reaching its targeted location in some disease prevention or treatment applications it may require a more precise targeted delivery to an intended site even at the cellular level to achieve the above stated objective one of the key inventive aspects of this patent application is to integrate micro containers injectors sensors positioning device motion apparatus communications devices and other various components with one to multiple ic devices with memory and logic processing functions on the same micro device to achieve far greater functionality precision selectivity and flexibility than those by conventional drug delivery.
